Answer:
angle 1 = 111
angle 2 = 69
Step-by-step explanation:
Supplementary Angles add up to 180°.
We are given angle 1 = (x+88)° and angle 2 = 3x°
The sum of both angles add up to 180°
x+88+3x=180
4x=180-88
4x=92
x = 23
To find angle 1, substitute x = 23 in (x+88)°
23°+88° = 111°
Therefore, angle 1 is 111°
To find angle 2, substitute x = 23 on 3x°
3(23) = 69°
Checking if the answer is right by combining 111 and 69.
111+69 = 180
Hence, the answers are 111° and 69°.
