Answer:
A = 21
Step-by-step explanation:
Complementary angles add to 90
x-21 + 2x-15 = 90
Combine like terms
3x -36 = 90
3x-36+36 = 90+36
3x = 126
Divide by 3
3x/3 =126/3
x = 42
We want to find ZA = x-21
A = 42-21
A = 21
I’m so sorry I really don’t know the answer but see if the Internet help
Answer:
undefined
Step-by-step explanation:
We can find the slope of a line using two by using the following
m = (y2-y1)/(x2-x1)
= (-2 - -3)/(6-6)
= (-2+3)/( 6-6)
=1/0
We cannot divide by 0 so the slope is undefined

Answer:
A
120
Step-by-step explanation:
With all the parallel lines involved, the central figure is a parallelogram. These 4 sided figures have the odd property of having their opposite angles equal.
What that means, in plain English is that <NRL = <NML
Both of these angles = 120
Here's the cruncher. <NRL and <PRK are vertically opposite. They are therefore equal.
The answer to your question is 120 which is A
