Answer:
20/5 = x /4 x = 80/5 = 16
x - 10 / 39 = 5/15 = 1/3
3x - 30 = 39
3x = 69
x = 23
(2x + 10 ) * 4 = 10 *(x + 3)
8x + 40 = 10x + 30
2x = 10
x = 4.
AE = 2(5) + 10 = 20, hope this helped.
the answer is 60 :) good luckStep-by-step explanation:
Step-by-step explanation:
180° = m<A + m<B + m<C
180° = 45° +60° + m<C
180° = 105° + m<C
m<C = 180° - 105 °
m<C = 75°
A=148°
B=148°
Step-by-step explanation:
180-38=148°
because A and B are equal, they're both 148°
0.8

24*0.3=7.2
than 8 he had , so whats left over
8-7.2=0.8
