ACD and ACE are supplementary angles that need to equal 180 degrees
ACE = 180 -100 = 80 degrees.

The first one and it's written as a(-1)(n-1). The parenthesis around the n-2 are important
Answer: The measure of angle S is 62 degrees.
There are 2 ways to find the answer.
First, the triangles are similar. That means that all the angles will be the same. Since, angle S is corresponding to angle B, it will have the same measure.
Second, there are always 180 degrees in a triangle. Therefore, we can write and solve the following equation about the angles in triangle SQR.
x + 41 + 77 = 180
x + 118 = 180
x = 62
The length of the line would be 2 1/16
