Answer:
A. Measure of angle A + measure of angle B
Step-by-step explanation:
Because angle 4 is an exterior angle of given triangle which will be equal to the Measure of angle 2 + measure of angle 3
Answer: x=5 y=6
Step-by-step explanation: 6y=3× +21
6y-6=2× +20
Opposite sides of the rectangle are equal
Substitute 3x +21 into 6y in the second equation.
Answer: c is perpendicular to y = -5x - 2
Explanation: The slope of a perpendicular line is an opposite reciprocal of the original slope/line. (Basically switch the numerator and denominator and the sign. In this case, the slope is -5/1x. It’s opposite reciprocal is 1/5x.)
You can take a look at my notes for further clarification. Hope this helps!
Answer:
x = 43
Step-by-step explanation:
180 - 65 = 115
115 = x + 72
<u>-72 -72 </u>
43 = x
x = 43
Answer:
24 cubic inches.
Step-by-step explanation:
The volume of one cube = s * s * s or s^3
s = 2 inches
V = s^3
V = 2 * 2 * 2 or 2^3
V = 8 cubic inches.
The volume of 3 of them is 8*3 = 24 cubic inches.
