Question

PLEASE HELP! ITS DUE SOON!!!! I DONT GET THIS!!!

Answer 1

Answer:

d. 50°

Using Sine rule:

$\sf \dfrac{sin(A)}{a} = \dfrac{sin(B)}{b}$

Insert the values:

$\rightarrow \sf \dfrac{sin(36)}{11.9} = \dfrac{sin(D)}{15.6}$

$\rightarrow \sf sin(D) = \dfrac{15.6 \ sin(36)}{11.9}$

$\rightarrow \sf sin(D) = 0.770542$

$\rightarrow \sf D = sin^{-1}(0.770542) = 50.4 \quad \approx \quad 50^{\circ \:}$
