An easy way to think of this when you solve this, is to remember that all the angles in a triangle add up to 180 degrees. Therefore, the equation would be
(3x + 10) + (2x + 10) + 45 = 180. By the way, since the angles D and B are across from each other they are congruent. Now, let’s start solving it:
(3x + 10) + (2x + 10) + 45 = 180
(5x + 20) + 45 = 180
5x + 65 = 180
5x = 115
x = 23
Answer:

Step-by-step explanation:
If we have an equation
and we want to find what b is in relation to a, we can change the equation so that we have b on one side and whatever is on the other side is what b is.

To isolate b, we can take the square root of both sides as taking the square root of something squared results in the base.


So b is the square root of a.
