Question

I need help on how to solve

Answer 1

Answer:

94 degrees

Step-by-step explanation:

triangle is 180

so 180-74-20=86

The exterior angle is 74+20=94

94 is exterior angle

Answer 2

Answer:

x = 94°

Step-by-step explanation:

Any triangle has three angles whose measures add up to a total of 180°.

This triangle has two known angle measures. First, find the missing interior angle measure.

180 - (74 + 20)

180 - 94

86

The missing interior angle's measure is 86°. An exterior angle is supplementary to its adjacent interior angle, which means that the measure of the interior angle plus the exterior angle measure is 180.

180 - 86

94

Another way to find out a missing exterior angle measure is to simply add the measures of the two nonadjacent interior angles.

74 + 20

94

I hope this helped :)
