U use sin
sin50 = b/10
b=10(0.76)
b=7.6
17\20 should be the correct answer
Rearrange the equation for like terms:
7b - 4b <span>- 3b </span>+ 3 + 5 + 2
= 10
<span>3x2− 5x + 5 = 0.
a=3 b=-5 c=5
A. a = 3, b = 5, c = 5
B. a = 3, b = −5, c = 5
C. a = 5, b = −5, c = 0
D. a = −3, b = 5, c = −5
answer is B
