Answer:
Step-by-step explanation:
in a square pyramid the base area plus the area of the triangular faces is equal to the total area so we take (9*5) *1/2=22.5 then we multiply 22.5 *4= 90 so we take 90 + 5*5 = 115 so the total area is 115
So in a kite the total angles will add up to be 360°
Angles F and H are congruent (they are the same angle) so they will be the same number of °.
The formula we can use to find F and H is:
87+31+2x=360
(F and H are represented by 2x because they are the same angle twice).
Solving formula:
87+31+2x=360
118+2x=360
2x=360-118
2x=242
2x/2=242/2
x=121
So now we know both angle F and H equal 121° Hope this help! Comment if you have anymore questions
Answer:
(x +3)^2 + (y -3)^2 = 3^2
Step-by-step explanation:
Your first task is to find the center.
The longest possible line of the circle goes from (-3,0) to (-3,6)
So the center is at the midpoint of these two points.
The midpoint is at (-3 - 3)/2 , (6+ 0)/2 or (-3,3)
That gives you the center of the circle.
So far what you have is
(x +3)^2 + (y -3)^2 = r^2
Now the distance of the center to the bottom point is (-3,3) to (-3,0)
r^2 = (x2 - x1)^2 + (y2 - y1)^2
x2 = - 3
x1 = - 3
y2 = 3
y1 = 0
r^2 = (-3 - -3)^2 + (3 - 0)^2
r^2 = 3^2
The entire answer is
(x +3)^2 + (y -3)^2 = 3^2
