Answer:
50 deg
Step-by-step explanation:
In an right triangle, the acute angles are complementary. That means their measures have a sum of 90 deg.
m<C + m<B = 90
7x - 20 + 4x = 90
11x = 110
x = 10
m<ACB= 7x - 20
m<ACB = 7(10) - 20
m<ACB = 70 - 20
m<ACB = 50
Answer: m<ACB = 50 deg
Answer:

Step-by-step explanation:
Suppose we have a triangle WXY whose internal angles are:



The sum of the measures of the angles must be 180°, thus:

Simplifying:
15x + 15 = 180
Subtracting 15:
15x = 165
Dividing by 15:
x = 11
Thus, the measure of angle Y is


Answer:
A. x + y > 30 8x + 10y ≥ 450
Step-by-step explanation:
x+y bunnies and puppies has to be greater than 30 (in amount)
the amount of money need to be greater than or equal to 450 for both x bunnies and y puppies.
The rate would be
22000 gallons per 16 hours or
rate = 22000/16 = 1375 gallons/hr
There is no ones place after the decimal so 3 is in the tenth place, so 2.4
