Question

Someone help me with this, please!

Answer 1

`26.4\º`

Explanation:

`\theta=?`

`$\sin(\theta)=(opp)/(hyp) = (4)/(9) $`

`$\theta=\sin^(-1)(4)/(9) =\arcsin(4)/(9) \approx 26.4\º$`

Answer 2

B = 26.4

Explanation:

Since this is a right triangle, we can use trig functions

sin theta = opp/ hyp

sin B = 4/9

Take the inverse sin of each side

sin ^-1 sin ( B) = sin ^-1 ( 4/9)

B = 26.38779996

B = 26.4
