Answer:
Step-by-step explanation:
Step1- Well first we have to find x and this is by using the following equation:
(8x+2)+(9x+3)+90=180 (because the sum of angles in a triangle is 180 degrees)
Expand the brackets and open them:
8x+2+9x+3+90=180
Arrange and then solve:
8x+9x+90+3+2=180
17x+95=180
17x=180-95
17x=85
x=85/17
x=5
Step2- Substitute the value of x in both equations:
8x+2=8(5)+2=40+2=42
Therefore, the first variable is 42degrees
9x+3=9(5)+3=45+3=48
Therefore, the second variable is 48 degrees
