What is the measure of angle of 1?

m<1 = 118

Step-by-step explanation:

The remote angles theorem states that when one extends one of the sides of a triangle, the sum of the two non-adjacent angles is equal to the measure of the angle between the extension of the side and a side of a triangle. One can apply this theorem here by stating that

(28) + (90) = m<1

Remember, a box around an angle signifies that its measure is (90) degrees.

Solve this problem by performing the operation,

118 = m<1

115 degrees

Step-by-step explanation:

90 degrees + 25 degrees = 115 degrees

CHECK YOUR ANSWER:

180 degrees - 115 degrees = 65 degrees

 180

-  65

= 115 degrees
