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?

Answer:
Option 2:
Step-by-step explanation:
Given:
From the triangle shown below;
A triangle QRS with angle QRS = 90°, ∠QSR = 30°.
Side QR = 5, SQ = 10 and RS = 5√3
Now, we know from trigonometric ratio that,
Here, opposite side of angle QSR is QR and Hypotenuse is the side opposite angle QRS which is SQ. Therefore,
Therefore, the value of sine of 30° is one-half. So, second option is correct.
