Unclear.
To find the perimeter you need all three sides of the triangle. You have only given two.
All you need to do is add up all three sides and you have your perimeter.
Formula: <u>P=a+b+c</u>
Answer:
We set up 2 equations
A) C + A = 100
B) 5C + 12A = 780
We multiply A by -5
A) -5C -5A = -500 then we add B
B) 5C + 12A = 780
7A = 280
Number of Adults = 40
5C = 780 - 40*12
5C = 780 -480
5C = 300
Number of Children = 60

Step-by-step explanation:
Using the cosine ratio in the right triangle
cos X =
=
=
, then
∠ X =
(
) ≈ 44° ( to the nearest degree ) → A
First, u find conman denominator which is 15 so 2/5=6/15 & 1/3=5/15, which adds up to 11/15, so the remaining fraction that kendrs has to wash is 4/15
