two angles are supplementary. what are the measures of two angles if the measure of the first angle is 40 more than half the second angle

and

Step-by-step explanation:

Two angles that are supplementary mean that they both add up to 180°.

If one angle is 40 more than half the second angle then,

a = + 40

Both angles together would be:

180 =

Step 1 - Subtract 40 from both sides of the equation:

Step 2 - Multiply both sides by 2:

Step 3 - Divide both sides by 3:

Step 4 - Plug this into the original equation to calculate the angle:

Therefore the two angles are:
