Question

If a pair of supplementary angles has the measures: 2x° and (x+30)°, what is the measurement of the larger angle?

Answer 1

Hey Brainly user

Here is your answer

$2x + x + 30 = 180$

$3x + 30 = 180$

$3x = 180 - 30$

$3x = 150$

$x = 50$

so those two angles are 2x=2(50)

»100

another angle x+30=50+30=80

The largest angle is 100 degrees
