Answer:
The only correct option is:
Option B. The perpendicular bisectors for each side are the only lines of reflection.
Step-by-step explanation:
A regular polygon has an odd number of sides. Which statement is true about the lines of reflection for the polygon that will map the shape onto itself?
A.
Lines that connect pairs of opposite vertices are lines of reflection.
B.
The perpendicular bisectors for each side are the only lines of reflection.
C.
The lines of reflection are parallel to the sides of the polygon.
D.
There are no lines of reflection.
The only correct option is:
Option B. The perpendicular bisectors for each side are the only lines of reflection.
Solution:
<u>Note that:</u>
- Area of triangle = 6 3/8 yd²
- Height of triangle = 2 1/2
- Area of triangle = 1/2 x base x altitude
<u>Use the formula to find the base of the triangle.</u>
- 1/2 x base x altitude = 6 3/8 yd²
- => 1/2 x base x 2 1/2 = 6 3/8 yd²
- => 1/2 x base x 5/2 = 6 3/8 yd²
- => 5/4 x base = 6 3/8 yd²
- => base = 6 3/8 ÷ 5/4 yd
- => base = 51/8 x 4/5 yd
- => base = 51/2 x 1/5 yd
- => base = 51/10 yd
The length of the base is 51/10 yards.
