Question

This is an assignment for my son who is having trouble doing the steps to solve these math problems.

Answer 1

B, C, B, A, B

Explanation:

Recall soh cah toa

sin - > soh sin(ANGLE) = opposite/hypotenuse

cos -> cah cos(ANGLE) = adjacent/hypotenuse

tan -> toa tan(ANGLE) = opposite/adjacent

(letters correspond)

7) They ask for sinX, meaning we need to apply soh

sinX = opposite/hypotenuse

sinX = 30/34 = 15/17

B

8)

tan(ANGLE) = opposite/adjacent

tanZ = 12/35

C

9)

cos(ANGLE) = adjacent/hypotenuse

cosZ = 36/45 = 4/5

B

10 + 11 are attached. Hopefully, you understand. Have a nice day :)
