x= -3
Step-by-step explanation:
Solve the rational equation by combining expressions and isolating the variable x.
Answer:
Below in bold.
Step-by-step explanation:
300 degrees - reference angle is |360 - 300 |= 60 degrees
225 = 225 - 180 = 45 degrees
480 = 480 - 360 = 120 so it is 180 - 120 = 60 degrees.
-210 = |-210 + 180| = 30 degrees.
Answer:
YA if you said it first ya you are supposed to get brainlies ONLY if the question says will give brainliest if your right
Step-by-step explanation:
Answer:
-1.
Step-by-step explanation:
1/m = m^-1.
We can show this is correct if we simplify the following:
m^2 / m ^3 = m * m / m * m* m = 1/m
By the law of indices: m ^2 / m^3 = m^(2-3) = m^-1.
Answer:
|CE|=2
Step-by-step explanation:
The quadrilateral is shown in the attachment
Recall that the diagonals of a rectangle are congruent.
This implies that:
|AC|=|BD|
We substitute the expressions to get:
This is now a linear equation in one variable.
Group similar terms to get:
Simplify to get:
15=3x
Divide both sides by 3 to get:
Recall again that the diagonals of a quadrilateral bisect each other.
Plug x=5
