1
Refresher on Solving with Lines and Angles
*set expressions equal to each other?
*total them to 180?
*total them to 90?
2
Given Parallel Lines, solve for q.
These angles are CORRESPONDING angles which are congruent
7q+4=3q+19
4q = 15
q = 3.75
3
Given Parallel Lines, solve for s.
These angles are SAME SIDE INTERIOR angles, so they total 180.
2s + 3s - 20 = 180
5s = 200
s = 40
4
Linear Pairs are 2 adjacent angles that form a straight angle
3x+5 + x+15 = 180
4x = 160
x = 40
y+20 + 4y-15 = 180
5y = 175
y = 35
5
Triangle Sum = 180
The m<BCA is 34 (linear pair)
5y+3 + 4y+8 + 34 = 180
9y = 135
y = 15
