Because they are the same angle and both equal 90 degrees.
Answer:
I got the same question on Khan Academy. I was going to ask that too but saw that you already did. Maybe try to point it out to someone else on Brainly. Sorry that I could not help.
Step-by-step explanation:
Answer:
y=15
x=43
(any variable can be used, I used x and y to make it easier to show)
Step-by-step explanation:
x+y=58
x-y=28
get x by its self
x=58-y
then subsitute into the other equation
(58-y)-y=28
58-2y=28
-2y=-30
y=15
sub. again
x+15=58
x=43
Answer:
43
Step-by-step explanation:
Given
2(p - q) + 5(p + q) ← substitute p = 7 and q = - 2 into the expression
= 2(7 - (- 2)) + 5(7 + (- 2))
= 2(7 + 2) + 5(7 - 2)
= 2(9) + 5(5)
= 18 + 25
= 43
Hello, let's figure this one out together.
Me, myself had to write this down in the notes form to understand what I was doing.
In the fraction, multiply the 2's by 3.
1 over 2(2^3)+5.3(3)
1 over 2(2^3)+(5.3)(3)
Simplify each by step.
You end of up with a decimal.
You have a total of 0.031348.
