4 is 20% of 20. Hope this helps!
<span>1 perpendicular bisector divides 1 side of the triangle into two equal lengths at a 90 degree angle. So if there's is three perpendicular bisectors, then it splits all three sides the triangles into equal lengths.
Angle bisectors splits an angle of a triangle into two even degrees.

<span>EX: if it is an equilateral triangle, each angle will be sixty degrees. Therefore, ONE angle bisector will split ONE of the angles into even degrees of thirty degrees. </span>
Rounding numbers means you change the number to a closer, easier number. For example if you want to round 56 to the nearest tenth, it would round to 60.
Estimating numbers is when you guess numbers. For example, if you want to estimate the measure used to measure a bed, i would estimate feet.
I hope this helped:))
Answer:
x=17
Step-by-step explanation:
VS is a straight line so it equals 180 degrees
The arc with be 180 degrees
VR + RS = 180
45+ 6x+33 = 180
Combine like terms
78+ 6x = 180
Subtract 78 from each side
78+6x-78 = 180-78
6x = 102
Divide each side by 6
6x/6 = 102/6
x =17
