Answer:
∠ A = 56°
Step-by-step explanation:
the sum of the 3 angles in a triangle = 180°
sum the 3 angles and equate to 180
2x + 3x + 40 = 180
5x + 40 = 180 ( subtract 40 from both sides )
5x = 140 ( divide both sides by 5 )
x = 28
then
∠ A = 2x = 2 × 28 = 56°

Answer:
9
Step-by-step explanation:
x² − 36 = 5x
x² − 5x − 36 = 0
(x − 9) (x + 4) = 0
x = 9 or -4
