Solve for x round to the nearest tenth of degree if necessary

x = 1 degree

Step-by-step explanation:

Using the Pythagorean theorem, we can find the unknown side then use SOHCAHTOA to find the unknown angle

First step:

Take the square root of both sides

Now to find the angle use SOHCAHTOA

Cosine = (The side we found is adjacent)(Hypotenuse is the longest side)

            =

             = 0.999

Approximately 1 degree.

the answer is d

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
