Step-by-step explanation:
The question is incomplete, as the sector, its area and the angle at the center are not given.
I will solve this using the following illusration
The area of a sector is:

Assume that:


The equation becomes

Simplify

Take: 

Cross Multiply

Solve for 


Take square roots


160/55.
Simplified version is 32/11
Because the two angles equal each other:
80=20x and solve for x
These are corresponding angles
Answer:
A. -1/8 x + 3/16
Step-by-step explanation:
Distribute -1/2 over the parentheses
-1/2 ( 1/4 x - 3/8 )
-1/2 (1/4 x) - 1/2 (-3/8 )
multiply fractions to simplify
-1/8 x + 3/16
A is correct
Step-by-step explanation:
One interior angle of a triangle = 30⁰ .
The measure of other two are x and y .
We know that the angle sum property of a triangle is 180⁰ .
=> x + y + 30⁰ = 180⁰
=> x + y = 180⁰ - 30⁰.
=> x + y = 150⁰.
Possible solution set of x and y are ,
(1,149) (2,148 ) ...... (148+2) & (149+1)
Basically we are here decreasing y and increasing x to obtain the values .
