DENIUS [597]

Answer:

$\theta=36.43^{\circ}$

Step-by-step explanation:

Given that,

Base = 42

Perpendicular height = 31

We need to find the value of $\theta$ . It can be calculated using trigonometry as follows :

$\tan\theta=\dfrac{P}{B}\\\\\theta=\tan^{-1}(\dfrac{P}{B})$

Put all the values,

$\theta=\tan^{-1}(\dfrac{31}{42})\\\\\theta=36.43^{\circ}$

So, the value of $\theta=36.43^{\circ}$ .
