The answer would be 50 + 13 = 63
Answer:
C x=40, y=30
Step-by-step explanation:
Remember the opposite side of parallelogram is the same
so angle C and angle A is the same.
3x=120
divide both sides by 3 and you get 40
All parallelogram equal to 180 degrees so to find y
180=2y+120
-2y=120-180
-2y=-60 negative divide negative is positive.
y=30
Answer:
Step-by-step explanation:
We have two sides
and the preimeter
We can calculate the length of the third side:
substitute
Use the Heron's formula:
where
substitute:
You'd have to find the average! (:
So add 14 and 16 to get 30, so your answer would be x/30
Since there are 14 boys, that would be x. 14/30 Simplify that to get 7/15!
