Question

angle X and angle Y are supplementary angles angle Y measures 65° what is the measure of angle X

Answer 1

Answer:

115

Step-by-step explanation:

Supplementary angels add up to 180, so if Y is 65, 180-65 is 115

Answer 2

Answer:

∠x = 115°

Step-by-step explanation:

• supplementary angle : either of two angles whose sum is 180°

x + y = 180

x + 65 = 180

to find the value of x:

x + 65 = 180

x = 180 - 65

x = 115
