The answer to the question is the first, third and fifth
Answer:
540°.
Step-by-step explanation:
On a unit circle, cos θ = -1 at 180°.
However, cos θ has a period of 2π, or 360°. This means that cos θ will equal to -1 again after 2π.
To solve for the angle:
180° + 360° = 540°. This is the next angle at which cos θ = -1.
Answer:
a=-7.68
Step-by-step explanation:
3a+13.61=-9.43
-13.61
_____________
-23.04
3a=-23.04
-23.04/3= -7.68
A-4b that’s my answer hope this help
By making a the subject of formula in the given equation, the value "a" is equal to 1/(56Q + 32GQ).
<h3>What is an equation?</h3>
An equation can be defined as a mathematical expression which shows that two (2) or more thing are equal.
In this exercise, you're required to solve for a from the given mathematical expression (equation) by making it the subject of formula. This ultimately implies that, all the other variables would be defined in terms of a and they would all be on the same side of the "equal to" symbol.
Making a the subject of formula, we have:
-4G + 1/8Qa = 7
1/8Qa = 7 + 4G
Multiplying both sides by 8Q, we have:
8Q × 1/8Qa = (7 + 4G) × 8Q
1/a = 56Q + 32GQ
a = 1/(56Q + 32GQ).
