What is the measure of the missing angle?

a. 222

b. 48

c. 132

d. 42

D. 42 degrees

Step-by-step explanation:

One angle is a right angle, so its measure is 90 degrees.

An exterior angle measures 132 degrees. That exterior angle is supplementary to one of the interior angles of the triangle.

180 deg - 132 deg = 48 deg

The interior angle adjacent to the 132-deg exterior angle measures 48 deg.

The measures of the interior angles of a triangle add to 180 deg.

90 + 48 + ? = 180

138 + ? = 180

? = 180 - 138

? = 42

42 degrees

the answer to your question a or b but i am pretty sure it is b. i hope this : )
