Using the identity:

, we get:

There are two solutions to this equation:
1) 
Since the period of cosine is 2π, so 0 + 2π = 2π will also be a solution to the given equation
2)
Therefore, there are 3 solutions to the given trigonometric equation.
The 'Y' Coordinate is written second in an order of coordinates which is /X , Y\ Prob such as /12, 5\
Answer:
5
Step-by-step explanation:
B and D are congruent. Set them equal to each other.
15x + 5 = 16x - 2
x = 7
Plug into B.
15(7) + 5 = 110
180 - 110 = 70
12y + 10 = 70
12y = 60
60 / 12 = 5 = y
Answer:
2: add 4
3: 6
5: multiply by 2
6: 7
Step-by-step explanation:
7/10-1/2 in simple form. so the two fractions have different denominators so you need to multiply both denominators 10x2 = 20 so both fractions have 20 on the bottom so they are like this now: 7/20-1/20= 6/20 simplify by 2: 6/20 divide by 2/2 =3/10. 3/10 is your answer
