∠xangle, x and ∠ y ∠yangle, y are supplementary angles. ∠ y ∠yangle, y measures 13 9 ∘ 139 ∘ 139, degrees. What is the measure of ∠ x ∠xangle, x

41°

Step-by-step explanation:

Supplementary angles are angles that has their sum total of angles as 180°.

If two angles ∠x and ∠ y are supplementary, this means

∠x+∠y = 180° ... (1)

Since ∠y = 139°, to get ∠x, we will substitute the value of ∠y in equation 1 to have;

∠x + 139° = 180°

∠x = 180°-139°

∠x = 41°

Therefore the measure of ∠x is 41°

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
