Question

These are questions about triangles. The teacher has already done one but I don’t know how to do the rest. Please help me! :(

Answer 1

Explanation:

To help you, Remeber the SOHCAHTOA rule

1. When It asked to find sin, cos, tangent of a angle
2. If you finding the sin of a angle you must find the side that is Opposite then put it over the hypotenuse
3. I'll do 3,6,7,8 for you.

For 3,The side that is opposite of c is 28 and the hypotenuse (which is the longest side of the triangle) is 35. So the answer is 28/35. or 4/5.

For 6, 32 is opposite of A and 40 is the hypotenuse so

32/40 or 4/5 is our answer.

For 7, 24 is opposite of Z and 40 is the hypotenuse so

24/40 or 3/5 is the answer.

For 8, 14 is opposite of Angle C and 50 is our hypotenuse so

14/50=7/25 is our answer

COS

To find cos it is adjacent/hypotenuse

For 2 the adjacent side to C is 16 and the hypotenuse is 34. so our answer is 16/34 or 8/17.

For 5, the adjacent side is 30 and the hypotenuse is 34 so our answer is 30/34 or 15/17

For 9, the adjacent side is 24 and hypotenuse is 30 so our answer is 24/30 or 5/6.

TAN

TO FIND TAN, it is Opposite/Adjacent

4, the opposite side is 32 and the adjacent is 24 so our answer is 32/24 or 4/3.

10, the opposite side is 27 and the adjacent is 36 so our answer is 27/36 or 3/4
