The correct answer is A to this question
Answer:
Theta = 120 degrees, 420 degrees, 480 degrees, 780 degrees, and 840 degrees
60 + 360 = 420 degrees,
60 + 720 = 780 degrees,
120 + 360 = 480 degrees,
120 + 720 = 840 degrees
Step-by-step explanation:
90 to 870 degrees for theta.
sin (theta) = root(3) /2
We see this comes from a 30-60-90 triangle.
theta is 60 degrees
but we want theta from 90 to 870 degrees.
120 degrees works too.
so we try to find all the co-terminal angles to 60 and 120 degrees that satisfy the conditions.
60 + 360 = 420 degrees,
60 + 720 = 780 degrees,
120 + 360 = 480 degrees,
120 + 720 = 840 degrees
Answer:
Step 1: Box A
Step 2: Box C
Step 3: Box A
Step 4: Box B
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
Given
= 8 + 4A
Multiply through by 3 to clear the fraction
2A = 24 + 12A ( subtract 12A from both sides )
- 10A = 24 ( divide both sides by - 10 )
A = - 2.4 → A
Answer:
-30x
Step-by-step explanation:
The parenthesis is just to multiply, and you can combine like terms. So -5*6=-30, which you multiply with x to get -30x.
