An hour and 15 minutes i believe. not 100% though
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.
The answer selected is the correct answer because all of the other ones are equivalent to each other.
Answer:
n = 143
Step-by-step explanation:
To find the value of n, you multiply 13 by 10 because that is the inverse of dividing, and you get 130. Since there is a greater than sign, the answer is 143 because the value of n has to be greater than 130.
A quadrilateral is a shape with four sides
We have two parallel sides with length 7cm and another two parallel sides with length 4cm
Four right angles
The shape is a rectangle
