I don't know what to do I'm very confused ​
finlep [7]

Answer:

x = 33.8°

Step-by-step explanation:

The resulting diagram we have is a right triangle. To find x, apply trigonometric function.

Reference angle = x

Opposite = 116

Adjacent = 173

Apply TOA:

Tan x = Opp/Adj

tan (x) = \frac{116}{173}

x = tan^{-1}(\frac{116}{173})

x = tan^{-1}(\frac{116}{173})

x = 33.8° (nearest tenth)

What is the measure of each interior angle in a regular 30-gon?
Rasek [7]
Exterior angles always add up to 360 degrees so for 30-gon each exterior angles is 12 degrees (360/30)

To get the interior angles you subtract 180 from 12 to get 168 degrees
