Answer:

x = 60

Step-by-step explanation:

Since the 3 sides of the triangle are congruent, then the triangle is equilateral with interior angles congruent and equal to 60°

x and the angle on the right of the triangle are alternate and congruent, so

x = 60

Hello!

The volume of a cone is Volume = 1/3πr²h.

V = 1/3π(10)²(9)
= 1/3<span>π100(9)
</span>= 1/3<span>π900
= 300</span>π cm³

Therefore, the volume of this right cone is 300<span>π cm</span>³.

PLEASE HELP ME QUICKLY!!! Given that N:{1,2,3,5,8,13} and M:{−9,−8,−6,−4,−2,4}, which statements about N and M are true?
Lelechka [254]

Answer:

The intersection of N and M contains only those elements that are in both N and M.

The intersection of N and M is ϕ.

​N∩M=∅

Step-by-step explanation:

Given

M = { 1, 2, 3, 5, 8, 13}

N = {-9, -8, -6, -4, -2, 4}

Now let us see each statement one by one.

The intersection of N and M contains only those elements that are in both N and M.

The statement is true because by definition intersection of two sets consists of common elements of both sets.

The intersection of N and M is ϕ.

The statement is true. As there is no common element in both sets.

The intersection of N and M is {−9,−8,−6,−4,−2}.

The statement is false because there is not common element in M and N.

N∪M=∅

The statement is false as the union consists of elements of both sets so it can't be empty.

​N∩M=∅

True. Because no common element so intersection will be an empty set..

Classify the following triangle
larisa86 [58]

Answer:

A. Right Triangle

D. Isosceles

Step-by-step explanation:

Well, since it has a square at the bottom of the triangle, it means it's a right triangle, because it has a 90 degree angle.

It is also an isosceles triangle, because two of the sides are of equal length.

Hope this helped!

55 over 3, or 55 wrestlers for every 3 rounds, but the wrestlers value is negative, thus 55 "less" wrestlers for every 3 rounds on average.
