Since angle C is not 90 degrees, it's one of the acute angles
in the right triangle.
(The side adjacent to angle C ) divided by (hypotenuse)
is the cosine of angle C .
(adjacent) / (10 inches) = cos(40 degrees)
Multiply each side by (10 inches):
Adjacent side = (10 inches) x cos(40) =
(10 inches) x 0.766 =
7.66 inches (rounded)
Answer:
12 liters
Step-by-step explanation:
Let the capacity sum of the 5 containers be X
13 = X / 5
X = 65 liters
Average capacity of the six = ( 65 + 7 )/ 6 liters
= 72/6 liters
= 12 liters
Step-by-step explanation:

Answer:
I think it would be y=x
Step-by-step explanation:
I might be wrong
X+y=30
x-y=12
add them together
x+y=30
<u>x-y=12+</u>
2x+0y=42
2x=42
divide 2
x=21
subsitute
x+y=30
21+y=30
subtrat 21
y=9
number sare 21 and 9
