Answer:
x = 9
<1 and <2 are verticales angles = 79 degrees
Step-by-step explanation:
<1 = <4 vertical angles
6x+25 = 10x - 11
25+11 = 10x - 6x
36 = 4x
36/4 = x
x = 9
<1 = 6(9)+25
<1 = 54 + 25
<1 = 79 degrees
Answer:
616 ft²
Step-by-step explanation:
Since the floor of the tepee is circular, we find its area by using the area of a circle.
So, A = πr² where π = 22/7 and r = radius of circular floor = 14 feet
So, substituting the values of the variables into the equation, we have
A = πr²
A = 22/7 × (14 ft)²
A = 22/7 × 196 ft²
A = 22 × 28 ft²
A = 616 ft²
So, the area of the floor of the tepee is 616 ft²
If the diameter is 12 inches and height be 15 inches then the slant height be 16.15 inches.
Given that the diameter be 12 inches and the height be 15 inches.
We are required to find the length of slant height.
The slant height of an object is basically a distance measured along a lateral face from the base along the "center" of the face.
We are given diameter be 12 inches so we have to first find the radius.
Radius=12/2 (Diameter is equal to twice the radius)
Radius=6 inches
Slant height is given as under:
Slant height=
=
=
=16.15 inches

Answer:
a=8+1/2
Step-by-step explanation:
We move all terms to the left:
(a+5)2/3-(9)=0
We multiply all the terms by the denominator
(a+5)2-9*3=0
We add all the numbers together, and all the variables
(a+5)2-27=0
We multiply parentheses
2a+10-27=0
We add all the numbers together, and all the variables
2a-17=0
We move all terms containing a to the left, all other terms to the right
2a=17
a=17/2
a=8+1/2
