Answer:
60x + 18
Step-by-step explanation:
8x - 4 [2x - 5 ( 3x + 1 )] - 2 [x - (x - 1)]
distribute
8x - 4 [2x - 15x - 5] - 2 [x - x + 1]
combine like-terms
8x - 4 [- 13x - 5] - 2 [1]
distribute again
8x + 52x + 20 - 2
combine like-terms again
60x +18
Step-by-step explanation:
a+b+c=180°
64°+b+c=180°
b=c
2b+64°=180°
2b=180-64
2b=116°
b=116/2
b=58°=c
4.6, 6.41, 6.46
