Answer:
10
Step-by-step explanation:
your is muplitying it 20
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)
I think the answer would be QR/XY=RS/YZ=QS/XZ
The answer is d)3 because each number gets multiplied by 3 to qual the next number
