The perimeter of a triangle is 24 cm.If it’s area is 24cm2 and it’s one of the three sides is 10 cm,find the sides of remaining
Answers
Answer:
The other sides are 6cm and 8cm
Step-by-step explanation:
Let the other 2 sides be x and y.
Using herons formula, we have an equation
24=sqrt(12*2*(12-x)*(12-y))
Since the perimeter is given, we have x+y=24-10=14. Solving it we have x=6,8 and y=8,6.

Margo bought the following lengths of ribbon: 3/4 yd, 1/3 yd, 1/2 yrd. How much ribbon did she buy?
Answers
Answer:
she bought 19/12 lengths of ribbon or aka 1 7/12
Step-by-step explanation:
3/4 + 1/3 + 1/2 = 13/12 + 1/2
13/12 +1/2 = 19/12
19/12 simplify is 1 7/12
Margo bought [tex]1\frac{2}{3}[/tex] yards of ribbon.
What is a fraction ?A fraction represents how much part of total quantity is present.Fractions are of two types proper fraction and improper fraction.
According to the question given Margo bought some ribbons of length 3/4 yd, 1/3 yd and 1/2 yd.
To find the total ribbon she bought in yards we have to take the sum of all the fractions.
∴ (3/4) + (1/3) + (1/2) yards.
Now to sum these fractions we have to take LCM of the denominators which is 12.
So, { (3×3) + (1×4) + (1×6) }/12.
= (9 + 4 + 6)/12.
= 19/12 or 1 whole 2/3 yards of ribbon.

Does anyone know the answer plz ?
Answers
Answer:
x = 5; y = 5
Step-by-step explanation:
One angle is a right angle, so its measure is 90 degrees.
One angle measures 45 degrees, so the unknown angle must also measure 45 degrees.
x and y are opposite two 45-degree angles, so x = y.
In a 45-45-90 triangle, the ratio of the lengths of the sides is
1 : 1 : sqrt(2)
We have
x : y : 5sqrt(2)
x/1 = 5sqrt(2)/sqrt(2)
x = 5
y = 5

Simplify the expression using trigonometric identities: sec (–θ) – cos θ.
Answers
Answer:
Step-by-step explanation:
Let's break this down. The secant of a negative angle is the same as the secant of the positive angle. This is because secant is the inverse of cosine, and cosine is an even function. f(-x) = f(x) if the function is even, and f(-x) = -f(x) if the function is odd. Sine is odd and has symmetry about the origin; cosine is even and has y-axis symmetry.
Therefore, sec(-θ) = sec(θ) and we have then
sec(θ) - cos(θ). Since secant is the inverse of cosine, we can write:
[tex]\frac{1}{cos\theta}-cos\theta[/tex] and finding a common denominator:
[tex]\frac{1-cos^2\theta}{cos\theta}[/tex] and using a trig identity:
[tex]\frac{sin^2\theta}{cos\theta}[/tex] and simplify that down a bit by breaking it up:
[tex]\frac{sin\theta}{cos\theta}*sin\theta[/tex] finally boils down to
tanθ · sinθ, the last choice there.

In order to form a parallel line, the two lines must have the same slope. Substitute the values into the point-slope formula to make the equation.
[tex]y-y_1=m(x-x_1)\\y-(-2)=-3(x-(-1))\\y+2=-3(x+1)\\y+2=-3x-3\\y=-3x-5[/tex]

crawl in a minute?
Answers
Answer: 2.1 cm per minute
Step-by-step explanation:
567/27 =21 mm
convert mm to cm (1mm = 0.1c,)
21mm = 2.1cm
Answer:
2.1 cm or 21 mm
Step-by-step explanation:
567 ÷ 27 = 21
Therefore the turtle can crawl 21 mm in a minute.
To covert mm to cm, we simply divide by 10.
21 ÷ 10 = 2.1
