Question

Find the value of each variable.

Answer 1

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
