Simon leans a 20 ft ladder against the side of his house so that the base of the ladder is
5 ft from the house. About how high up the side of the house does the ladder reach?
Round to the nearest tenth of a foot?
Answers
Most of the time when you try to find a missing length of a right triangle you use Pythagorean theorem. Pythagorean theorem is A squared plus B squared equals C squared. C squared is always going to be the longest length/diagonal line otherwise known as your hypotenuse. In this case the ladder is the hypotenuse. So instead of adding five squared +20 squared you’re going to square 20 and then subtract five squared to get the missing length which would be B squared and then you have to find the square root of B squared. So 20 squared is 4000. 5squared is 25 400-25 = 375 square root of 375 is about 19.4.

Step-by-step explanation:
Sum of angles of a triangle = 180
x + (180 - 105) + (180 -140) = 180

x = 180 -75 - 40

An isosceles right triangle is inscribed in a circle. The hypotenuse of the triangle is the diameter of the circle. Write a function f in terms of x that represents the area of the shaded region. Leave your answer in terms of π.
Answers
9514 1404 393
Answer:
f(x) = (π-2)x^2/4
Step-by-step explanation:
The area of the triangle is ...
A = 1/2(x)(x) = (1/2)x^2
The hypotenuse of the triangle is x√2, so the radius of the circle is x/√2. That means the area of the semicircle is ...
A = 1/2πr^2 = (π/2)(x/√2)^2 = (π/4)x^2
The shaded area is the difference between the semicircle area and the triangle area.
f(x) = (π/4)x^2 -(1/2)x^2
f(x) = (π-2)x^2/4

C. 1786.05 m^3
D. 3572.1 m^3
Answers
Answer:
the answer is d, sorry for the late answer, I just saw this
Step-by-step explanation:
ok so finding the volume of a prism, the formula for that is volume= base area * height or v=b*h
when I saw this problem I realized that I had to find the base area, in this case it's a hexagon. The formula for a regular polygon is A= 1/2 p*a p is perimeter and a is the apothem.
- I suggest you write those formulas down if you have trouble memorizing them.
So now time for the math!!!
so the perimeter of the hexagon is simply
[tex]7 \times 6 = 42 [/tex]
and the apothem is the perpendicular line so now simply plug those in to the polygon formula and you get...
[tex]42 \times 8.1 = 340.2[/tex]
[tex]340.2 \div 2 = 170.1[/tex]
now that you have the base area, simply plug in the height and area into the volume of a prism formula, and you get
[tex]170.1 \times 21 = 3572.1m ^{3} [/tex]
- I really hope this helps, I'm not the best at math and when I don't understand something it really stresses me out so pls ask questions if you have them :)
Zoe says an equilateral triangle is always an acute triangle, but an acute triangle is never an equilateral triangle. Which statement explains whether Zoe is correct or not?
Select one:
a. Zoe is not correct because equilateral triangles are acute triangles with three sides of equal length. Acute triangles can sometimes be equilateral triangles.
b. Zoe is not correct because equilateral triangles have three acute angles. Acute triangles have three acute angles, so acute triangles are always equilateral triangles.
c. Zoe is correct because equilateral triangles have three sides of equal length, and acute triangles have three sides of different lengths.
d. Zoe is correct because equilateral triangles have three acute angles. Acute triangles have one acute angle, so an acute triangle cannot be an equilateral triangle.
Answers
Answer:
D
Step-by-step explanation:
Zoe is correct because equilateral triangles have three acute angles. Acute triangles have one acute angle, so an acute triangle cannot be an equilateral triangle. Therefore, option D is the correct answer.
What is an acute angle?An acute angle is an angle that is less than 90°, and these angles can be measured using a protractor.
Triangles can be classified on the basis of angles and sides. An acute triangle is one that is classified on the basis of the measurement of angles. If all the interior angles of a triangle are less than 90°, then the triangle is said to be an acute triangle.
In equilateral triangle all three angles are equal, that is 60°.
Therefore, option D is the correct answer.

y · 100 = 450 · 7.25
100y = 3262.5

An access ramp to a building is 3.7 m long. The distance from beginning of the ramp to the base of the building is 3.5 m. How tall is the ramp?
Answers
Answer: 1.2 m
Step-by-step explanation:
Given
The length of the ramp to the building is 3.7 m
Distance from the beginning of the ramp to the base of the building is 3.5 m.
Suppose h is the height of the ramp
from the figure, we can write
[tex]\Rightarrow 3.7^2=3.5^2+h^2\\\Rightarrow 13.69-12.25=h^2\\\Rightarrow h^2=1.44\\\Rightarrow h=1.2\ m[/tex]
So, the height of the ramp is 1.2 m

Step-by-step explanation:
because 15 would be the base so 11 and 12 would be the sides and fot the triangle to be acute or obtuse the total of the sides (11+12) has to be lass than the base (15), but it is more 23 so it has to be a right triangle.
