Answer:
30 and 150
Step-by-step explanation:
The first angle is 30 degrees. The second angle is 150 degrees. Here's why:
Step-by-step explanation:
The first angle will be expressed as x. Since the second angle is 120
degrees greater than the first, it will be expressed as (x+120). Because they're supplementary, they'll add up to
180: x+(x+120)=180
Combine like terms.
2x+120=180
Subtract 120 from both sides.
2x=60
Divide by 2 to isolate for x.
x=30
Plug your data back in:
30 + (30 + 120) = 180
First angle: 30 degrees
Second angle: 150 degrees
