Answer 1

Answer:

[tex]x=5\sqrt{3}[/tex]

Step-by-step explanation:

Evaluate the Pythagorean Theorem for the triangle.

a² + b² = c²

5² + x² = 10²

25 + x² = 100

Subtract 25 from both sides.

x² = 75

Square root.

x = sqrt(75)

Expand the radical.

x = 5*sqrt(3)

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.

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

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
