Answer:
60 <u>and</u> 30
Step-by-step explanation:
Plug in each number into cos(θ) until your answer is 0.5 since sin(θ) is equal to 0.5.
sin(-30)=-0.5
sin(30)=0.5
sin(60)=0.5
sin(180)=0
Step-by-step explanation:

Actually none of them are the prime factors of 54.
A. indeed are factors, but neither of them are prime.
But you can break down A. into prime factors, 9 = 3*3, 6 = 3*2.
So now you have 3*3 * 3*2, which are all prime.
So the prime factorization of 54 is 3*3*3*2
2x + 6 = 4x/2 + 12/2
To solve this, we need to transpose like terms to the same side.
2x - 4x/2 = 12/2 - 6
2x - 2x = 6 - 6
0 = 0
Since both sides are zero, it means that the equation has infinite number of solutions.
Answer:
t = 1
Step-by-step explanation:
5t + 8 = 13
Subtract 8 from both sides
5t + 8 - 8 = 13 - 8
5t = 5
Divide both sides by 5
5t/5 = 5/5
t = 1
Check:
5t + 8 = 13
5(1) + 8 = 13
5 + 8 = 13
