In the diagram below, angles a and b are supplementary. The measure of angle a is 5x degrees and the measure of angle b is 2x + 40. How many degrees are in angle a? Show your work.

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides

step-by-step explanation:

are ya tryin to ask something or is this a statement

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
