Answer:
B
Step-by-step explanation:
AS is an angle bisector, thus the ratio of the sides of the triangle is equal to the ratio of the corresponding parts of RT, that is
= 
, substituting values
= 
( cross- multiply )
7.5x = 31.5 ( divide both sides by 7.5 )
x = 4.2
Thus
RT = 3.5 + x = 3.5 + 4.2 = 7.7 → B
Answer:
500 minutes
Step-by-step explanation:
100% = x
15% = 75
We multiply 75 by 100 and divide the answer by 15
7500 / 15 = 500 minutes
