Question

Use the given triangle to solve for x.

Answer 1

X=5

Angle c is 42 degrees

Explanation:

sum of all angles in a triangle equal 180 degrees so we set all these angles equal to that

(9x-3)+(22x+1)+(42-3x)=180

31x-2+42-3x=180

28x+40=180

-40. -40

28x=140

/28. /28

x=5

So now to find angle c we just fill in X

9(5)-3

45-3

42
