X - the percent of increase

The percent of increase is approximately 23.8%.
Answer:
B
Step-by-step explanation:
Interior angles of a triangle = 180°
3x°+3x+10°+4x-30°=180°
10x°-20°=180°
10x°=180°+20°
10x°= 200°
10x°/10=200°/10
x°=20°
We know here 147 out of 156 customers are not won so far
Probability of not winning=147/156
P not wining=0.94
so probability for winning is 1-P not wining
1-0.94= 0.057
if u want an answer is numerator and denominator so u just find 1-147/156<span />
