Solve for x:<br><br> x = <br> Answers: 22.5 30 45
AVprozaik [17]
Answer: 22.5 degrees

Step-by-Step Explanation:

As we can see, we are given a line, which is a straight angle. Hence, it will be of 180 degrees.

=> All the angles sum up to 180.

Therefore,
=> 3x + x + 90 = 180
= 4x + 90 = 180
= 4x = 180 - 90 = 90
=> x = 90/4 = 22.5

Therefore, x = 22.5 degrees

Verification:

=> 3x + x + 90 = 180
= 3(22.5) + 22.5 + 90 = 180
= 67.5 + 22.5 + 90 = 180
= 90 + 90 = 180
=> 180 = 180
=> LHS = RHS

You deck has an area of 128 square feet. After adding a section, the are will be s by the power of 2+128 square feet. Draw a dia
irga5000 [103]
You are adding s^2 to your 128 ft^2.  s^2 is a common representation of a square.  So you could think of it as adding an area of a square of side "s" to your deck.

So one way of drawing it is to draw a rectangle with area 128 ft^2 and attaching a square to one of its side.  The square that is attached has a side lenght of "s."
