Hi there!
To solve, we must use the following trig identity:
sin(u - v) = sin(u)cos(v) - sin(v)cos(u)
We can rewrite the left hand side of the equation as:

Split the fraction:

First fraction reduces to 1:

Simpify each with common arguments:

A) 60o because similar triangles have corresponding angles equal so then by Angle Sum Property of Triangles you will get 60o
Answer:
y=60x+14
Step-by-step explanation:
60 is the slope that is going UP at a certain rate and then ur adding 14
Answer:

Step-by-step explanation:
1) Flip the second fraction and change the operation to multiplication:

2) Cross cancel factors:

3) Multiply:

4) Simplify:
