Answer:
x=6
Step-by-step explanation:
Option C:
We can find the value of PR using law of cosines.
Solution:
Given data:
∠Q = 18°, r = 9.5, p = 6.0
To find which length could be find in the triangle:
Law of cosines:

Substitute a = q, b = r, c = p and A = Q

If we substitute the values given, we can find q.
q = PR

Hence we can find the value of PR using law of cosines.
Option C is the correct answer.
Answer:
their would be 19 marbles in each bag but the total left out the bag will be 28 which is explain below
731 ÷ 37= 19
19 × 37 = 703
703 - 731 = - 28

Given y = f(x)
Substitute x = 10.

Therefore f(x) = 13 when x = 10
