The answer is 30
You multiply 2 x 30 which is 60 and 60 + 30 = 90
hope this helps :D
The answer would be 3 cups of juice
The area of a parallelogram is the base times the height so:
A=bh, in this case:
A=hx
x=A/h, we are told that A=120mm^2 and h=10mm so
x=120mm^2/10mm
x=12mm
The given angles are complementary, therefore:
(5r + 5) + (8r -6) = 90°
13r - 1 = 90
13r - 1 + 1 = 90 + 1
13r = 91
13r/13 = 91/13
r = 7
