Answer:
The answer is C
Step-by-step explanation:
An isosceles triangle has two angles that measure the same, so...
30 + 30 = 60
180 - 60 = 120
No
____________
45 + 45 = 90
180 - 90 = 90
No
____________
60 + 60 = 120
180 - 120 = 60
Yes
____________
90 + 90 = 180
No
Answer:
2np + p²
Step-by-step explanation:
The general formula for the area of a square is A = s², where s = the length of one side of the square. In the case of the smaller square the area would be: n x n = n². Since the side of the larger square is 'p' inches longer, the length of one side is 'n + p'. To find the area of the larger square, we have to take the length x length or (n +p)².
Using FOIL (forward, outside, inside, last):
(n + p)(n+p) = n² + 2np + p²
Since the area of the first triangle is n², we can subtract this amount from the area of the larger square to find out how many square inches greater the larger square area is.
n² + 2np + p² - n² = 2np + p²
Answer:
D

I got it right on Khan Academy
I think the answer is True
The answer is the option A, which is: A. Equilateral triangles.
The explanation for this answer is shown below:
By definition, a tetrahedron is a solid in three dimensions that has: six sides, four vertices and four triangular faces. These faces are equilateral triangles, which means that all the sides are equal and all the interior angles measure 
degrees.
The tetrahedron is also called "triangular pyramid".
