Answer:
B.70
Step-by-step explanation:
For one or two angles are complementary angle(s), they have to equal 90°.
So, we need to find the larger angle, but what about the other?
Let x be the other angle and y be the angle we are looking for
x + y = 90
Lets look for x first, since one angle is ten less than four times the angle we are looking for or visa versa, we must:
y = 4x - 10
For an exchange, lets take out the y variable for another x variable:
So now we should have x + 4x - 10 = 90
Combine like terms and do cross equation :
x + 4x -10 = 90
5x - 10 = 90
Add 10 to both sides:
5x = 100
100/5 = 20
So <u><em>x=20</em></u>
<u><em></em></u>
Now for y which is what we are looking for,
y = 4x - 10
Since x is 20, plug it in
y = 80 - 10
y=70 is our larger angle

Answer:
y = 5x +4
Step-by-step explanation:
x has to equal 1
y = 5(1) +4 = 9
