Answer:
AB = 4.41
Step-by-step explanation:
→You are given the adjacent side and need to find the hypotenuse. For this, we use cos.
<u>→Set it up, like so:</u>
<u />
<u>→To get rid of the x in the denominator, multiply everything by x:</u>
<u />
<u>→Divide both sides by cos25:</u>
x = 4.413
<u>→Round to nearest hundredth:</u>
x = 4.41

<u>Explanation:</u>
Altitude of an equilateral triangle, H = 22 in
Perimeter, p = ?
Let a be the side of the triangle
We know:
Perimeter = 3a
P = 3 X 25.4 in
P = 76.2 in
Answer:
12
Step-by-step explanation:
using pythagoras theorem
here 15 is hypotenuse since it is opposite 0f 90 degree
9 and x are the other smaller sides of a triangle
according to pythagoras thorem the sum of square of two smaller sides of a triangle is equal to the square of hypotenuse. So,
9^2 + x^2 = 15^2
81 + x^2 = 225
x^2 = 225 - 81
x^2 = 144
x =
x = 12
