Answer:
b = 110°
Step-by-step explanation:
The sum of angles in a trapezoid is 360°
Summing the angles we get:
65°+55°+130°=250°
Then subtracting this value from 360° we get:
360°-250°=110°
Final answer of 110°
Answer:

We can see through alternate interior and exterior angles, corresponding angles, and vertical angles what the measures are.
Answer:

Step-by-step explanation:
Given:

Number line is from range -2 to 2 with all increment of ±
on both sides.
Step 1: First we will solve the equation we will get;

Step 2: Now we will try to make the denominator common so we will get;

Step 3: Now from the number line when we subtract 
from
we get number of spaces left are - 7
Hence now it will become:

Hence the final Answer is 
-7+(9)=2
you can do the opposite of what is given (9-7)
Answer:
r = ∛(3V/4π)
Step-by-step explanation:
The formula for the volume of a sphere is V = (4/3)πr³.
We want to solve this first for r³ and then for r.
Multiplying both sides of V = (4/3)πr³ by 3 yields an equation without fractions: 3V = 4πr³.
Dividing both sides of this equation by 4π isolates r³:
3V
r³ = -------
4π
To find r, take the cube root of both sides of
3V
r³ = -------
4π
obtaining r = ∛(3V/4π)
