A. 32.2°
B. 40.2°
C. 49.8°
D. 57.8°

Answer 1

Answer:

40.2

Step-by-step explanation:

Answer 2

Let's see

$\\ \rm\rightarrowtail tan\theta=\dfrac{Perpendicular}{Base}$

$\\ \rm\rightarrowtail tan\theta=\dfrac{11}{13}$

$\\ \rm\rightarrowtail tan\theta=0.846$

$\\ \rm\rightarrowtail \theta=tan^{-1}(0.846)$

$\\ \rm\rightarrowtail \theta=40.2^{\circ}$
