The base is 6.
In order to find this, we can set the legs equal to each other since legs have the same length in an isosceles triangle.
x + 1 = -x + 7
2x + 1 = 7
2x = 6
x = 3
Now that we have the value for x, we can plug into the equation to get the value for the base.
3x - 3 = base
3(3) - 3 = base
9 - 3 = base
6 = base
Answer:
(C)261.12 Square Inches
Step-by-step explanation:
The diameter of the Cone Hat = 6.6 inches
Radius = Diameter/2=6.6/2=3.3 Inches
The slant height = 8.4 inches.
To determine how many square inches of construction paper did Bree need to make the three hats, we find the Curved Surface Area of the Cones.
Curved Surface Area of a Cone 
Therefore, the area of paper used for the 3 hats
=3 X Area of One Hat
You has to make the botom number the same
to change the bottom number and maintain the same value of the fraction you has to multiply by 1 or x/x wher x=x
so
bottom numbers are 7 and 3
make them 21 by mutliply 5/7 by 3/3 and multiply -1/3 by 7/7
5/7 times 3/3=15/21
-1/3 times 7/7=-7/21
now we can do
15/21-7/21=(15-7)/21=8/21
answer is 8/21
Answer: Option C- 10
You are looking for the measure of the hypotenuse. So, use the Pythagorean Theorem to solve!
a^2 + b^2 = c^2
6^2 + 8^2 = c^2
36 + 64 = c^2
100 = c^2 <—- now take the square root
10 = c
