I need help writing the equations for these word problems, and maybe an explanation on how to write equations? I have a lot of t
rouble with it.

1. One angle of a triangle measures 120°. The other two angles are congruent. Write and solve an equation to find the measure of the congruent angles.
2. Linda is paid double her normal hourly rate for each hour she works over 40 hours a week. Last week, she worked 52 hours and earned $544. What is her hourly rate?

b)
Step-by-step explanation:
<u>Exercise 3</u>
<u>Exercise 4</u>
a) If L2 is parallel to L1, it has the same slope (gradient) ⇒
If L2 passes through point (3, 1):
So L2 = L1
b) If L3 is perpendicular to L1, then the slope of L3 is the negative reciprocals of the slope of L1 ⇒
If L3 passes through point (-5, 2):
