Complementary angles are angles that add up to 90 degrees. 2x is the first angle. Let y be the second one.
y+2x = 90
Subtract 2x from both sides.
y = 90 - 2x.
The second option is your answer. Have is nice day! :)

Find the unit rate for this painting:
3/5 of wall surface 3/5 15 9
------------------------------- = --------------- * --------- = -----------
(8/15) hour 8/15 15 8
Jane could actually paint the whole wall plus 1/8 more of it in one hour.
Hello,
A good method for solving this question is creating an equation to solve for the width of the door.
Let w = the width of the door
Let h = the height of the door
The height (h) is twice the width (2w) and one foot more (+1).
We can make the equation h = 2w + 1
Now, we are given that the height of the door is 7 feet, so h = 7.
We can simply plug in 7 for h in the equation to solve for w.
So, we have h = 2w + 1
7 = 2w + 1
Subtract by 1 on both sides to get:
6 = 2w
Divide by 2 on both sides to get:
w = 3
The width of the door is 3 feet.
However, we should check out answer with the given question to make sure it checks out.
We are given that the height of the door is one foot more than twice its width, and the height of the door is 7 feet.
Twice the width is 6 feet, and one foot more than that is 7 feet. Our answer checks out.
The width of the door is 3 feet.
Hope this helps!
