Two angles form a linear pair. the measure of one angle is 26∘26∘ greater than the measure of the other angle. find the measure

Tpy6a [65]

A linear pair means that the sum of the angles is 180 degrees.

Therefore:

a + b = 180°

We know that:

a = b + 26°

Therefore:

b + 26 + b = 180

2b = 154

b = 77°

So,

a = b + 26 = 103<span>°</span>

Answer:

55°

Step-by-step explanation:

x+x-20=90[Complementary angle]

or, 2x-20=90

or, 2x=90+20

or, 2x=110

or, x=110/2

x=55°
