Answer:
right angles.B
Step-by-step explanation:
let x and ybe angles.
x+y=180
also x=y
x+x=180
2x=180
x=180/2=90
y=x=90
Answer:
The slope is undefined
Step-by-step explanation:
we have that
The equation of the line s is equal to

This is a vertical line (parallel to the y-axis)
The slope is undefined
Because
The formula to calculate the slope between two points is equal to

we have

Substitute the values

------> is undefined
The point T is (5,-1)
The equation of the line parallel to the line s that passes through the point T, will be a vertical line and the equation is equal to the x-coordinate of point T
therefore
The equation is

Step-by-step explanation:
MEDIAN
71, 81, 89, 92, 93, 94, 94, 99
92 + 93 = 185 / 2 = 92.5
The median is 92.5
MODE
71, 81, 89, 92, 93, 94, 94, 99
The mode is 94
sorry i didn't understand the question a lot but i think the answer is <u><em>-1</em></u>.
p.s. i don't know if this is for sure right.
Answer:
Step-by-step explanation:
6y-42=4y
2y=42
y=21
6x-12=2x+36
4x=48
x=12
