Answer:
∠B = 52°
Step-by-step explanation:
Since we know that the sum of all inner angles of the triangle equal to 180°, then we can make the following equation,
5x + 3x + 2x + 20 = 180
10x = 180 - 20
10x = 160
x = 160 / 10
x = 16
Since we know that ∠B = (2x + 20)°, we can calculate the following
∠B = (2x + 20)°
∠B = (2(16) + 20)°
∠B = (32 + 20)°
me cause I want to play that game so bad
x + 2x + 6 = 27
3x + 6 = 27
x + 2 = 9
x = 9 - 2
x = 7
2 × 7 = 14
14 + 6 = 20
