Answer:
Step-by-step explanation:
Midpoint of the diameter is the center.
<u>Use midpoint formula to determine the coordinates:</u>
- x = (2 - 4)/2 = -1
- y = (5 + 13)/2 = 9
<u>Find the radius using the midpoint and one of the endpoints and the distance formula:</u>
- r =
<u>Use the equation of the circle:</u>
- (x - (-1))² + (y - 9)² = 5²
- (x + 1)² + (y - 9)² = 25
Correct choice is 4
The length of side of triangle is 5 units and length of side of pentagon is 1.5 units.
<u>SOLUTION:</u>
Given, An equilateral triangle has sides of length units.
Then, perimeter of the triangle will be
A regular pentagon (5 sides) has sides of units.
Then, perimeter of the pentagon will be
We have to find the dimensions of each shape
. Now, the perimeter of the triangle is twice the perimeter of the pentagon,
So,
Then, length of side of triangle
Length of side of pentagon
We have to neglect, negative sign as lengths can’t be negative. Even if we change the sign above all conditions are satisfied.
