Question

The exterior sides of two adjacent angles make

Answer 1

Answer:

a=28 degrees

b=62 degrees

Step-by-step explanation:

Use substitution.

Since we know a right angle = 90 deg, then a+b=90 (1st equation)

Our second equation is a+3=1/2b

subtract -3 to make a=1/2b-3, then plug in the a value into the a+b=90 equation. Then solve for b.

subtract the value that you got for b from 90deg to give you the value for a.
