Answer:
As
1/4×100 = 0.25×100 
             = 25%
Thus,
1/4 = 25%
Step-by-step explanation:
Given the fraction
1/4
- In order to write the fraction 1/4 as a percent, all we need is to multiply 1/4 by 100.
i.e.
1/4×100 = 0.25×100 
             = 25%
Therefore, we conclude that:
1/4 = 25%
 
        
             
        
        
        
Answer:
C
Step-by-step explanation:
because vertical angles angles that are opposite each other and formed by two intersecting lines are congruent

Answer: 80 degrees</h3>
===========================================================
Explanation:
Angle 3 and the 100 degree angle are corresponding angles. They are both in the southeast quadrant of their four-corner angle configuration. Assuming the lines that look horizontal are parallel, this would mean angle 3 is 100 degrees. Recall that corresponding angles are congruent when we have parallel lines.
Once we know that angle 3 = 100, we will use this to find angle 4.
Angles 3 and 4 add to 180. They form a straight angle or straight line.
(angle3)+(angle4) = 180
(100) + (angle4) = 180
angle4 = 180-100
angle4 = 80 degrees
