The two base angles of an isoceles triangle are equal so we can conclude that
2x - 20 = x + 8
Now we just need to solve for x:
2x - 20 + 20 = x + 8 + 20
2x = x + 28
2x - x = x + 28 - x
x = 28
So, angle B = x + 8 which is 28 + 8 = 36°
Answer:
2x and 7y, because they have different variables.
Step-by-step explanation:
Answer:
A) yellow = 4.5
B) pink = 8
C) orange =9
Step-by-step explanation:
A) yellow = 12-2-1-4.5=4.5
B) pink = 7 whole plus 2 half equals 8
C) orange = 16-1-1.5-1.5-3=9
