Anybody know how to do this ?

Hey there!

The interior angles of a triangle equal 180.

We can use this and the measures of the angles we are given to find the missing interior angle.

50+93=143

180-143=37

Since the missing angle (37) and angle x are supplementary, they add up to 180 as well.

37 + x = 180

180 - 37 = 143

x = 143

Hope this helps!

Answer:

$\theta \approx 1.23^\circ$

Step-by-step explanation:

The expression has been given as:

$tan(\theta) = \frac{50}{18}$

Required: Find $\theta$

Simplify the fraction

$tan(\theta) = 2.7778$

Take arc tan of both sides

$\theta = tan^{-1}(2.7778)$

$\theta \approx 1.23^\circ$
