3t+40=A
he starts with 40, so you add that to 3 t (3 meters every year-t)
Due to the Triangle Angle Sum Theorem, we know that the sum of the interior angles of a triangle is 180 degrees.
90 + 2x - 2 + x + 5 = 180 degrees.
Combine like terms.
3x + 93 = 180
Subtract 93 from both sides.
3x = 87
Divide both sides by 3
x = 29

Answer:
C. -12
Step-by-step explanation:
divide each side by 2/3
2/3x ÷ 2/3 = x
-8 ÷ 2/3 = -12
x = -12
