Question

Soh Cah Toa solve for x and round to the nearest tenth

Answer 1

x =5.1

Explanation:

For the angle 82, we know the adjacent side and the opposite side

tan 82 = opposite/ adjacent

tan 82 = 36/x

Multiply by x on each side

x tan 82 = 36/x*x

x tan 82 =36

Divide by tan 82

x tan 82/ tan 82 = 36 / tan 82

x = 36/ tan 82

x=5.059470049

To the nearest tenth

x =5.1
