→ Substitute cos 2x and sin 2x by their expressions

→ Subtract both sides by sin x

→ Take sin x as a common factor in the right side

From the graph, the equation has 4 solutions, the intersection points between the 2 graphs

Answer:
number 1 is 5x+8y+10
Step-by-step explanation:
Let's simplify step-by-step.
10y+3x+10+x+x−2y
=10y+3x+10+x+x+−2y
Combine Like Terms:
=10y+3x+10+x+x+−2y
=(3x+x+x)+(10y+−2y)+(10)
=5x+8y+10
Answer:
=5x+8y+10
The measurement of angle b is equal to 100
