Hello again! So we will be using the pythagorean theorem (
) to solve for the bottom leg of the triangles. After we do that, we'll subtract the value of the legs from 31, and that'll be x.
Plug in 17 and z (or any variable that isn't x) into the leg variable and 19 into the hypotenuse variable, and from there we can solve.
Solve the exponents to get
Subtract 289 on each side to get
Lastly, square root each side of the equation and your answer should be
(To get more accurate answers, you shouldn't round until the end of the problem)
Nextly, we will need to subtract
from 31. And since there are 2 triangles, you'll need to multiply
by 2.
In short, x = 14.0
Recall that the area of an equilateral triangle with side length is .
In the plane, the base is given by two equations:
so that for any given , the vertical distance between the two sides of the circle is
and this is the side of length of each triangular cross-section for each . Then the area of each cross-section is
and the volume of the solid is
Answer:
135 miles
Step-by-step explanation:

Answer:
B
Step-by-step explanation:
Answer:
you're lazy count the squares
Step-by-step explanation:
i think i counted 73. You can count the squares again. Then that is the area cm^2
the perimeter i counted 64
Count the edges of the squares and you'll get perimeter. I counted roughly so count carefully.
