Answer: 89
43 + x = 132 => Exterior Angle Theorem
^
The measure of an exterior angle of a triangle is greater than either of the measures of the remote interior angles. That means the two remote interior angle add up to the exterior angle.
x = 89
**To find the last angle: 89 + 43 + x = 180 => Triangle Sum Theorem states that the interior angles of a triangle add up to 180. The last angle would be 48.**
terms are t
and like terms are numbers
Answer:
hi there!
the correct answer to question is: x=-3
Step-by-step explanation:
you move -12x to the other side by adding it on both sides to get: -3x=9 then you divide -3 on both sides to get x=-3
