Answer:
A = 50
Step-by-step explanation:
All three angles are the interior angles of a triangle. No matter what else might be true, those three angles add up to 180 degrees. All triangles have interior angles adding up to 180 degrees.
8x + 8 + 5x + 5 + 4x + 14 = 180 Combine like terms
17x + 27 = 180 Subtract 27 from both sides.
17x = 180 - 27
17x = 153 Divide both sides by 17
x = 153/17
x = 9
But you want A
A = 4x + 14
x = 9
A = 4*9 + 14
A = 36 + 14
A= 50
