She is wrong because 340 and 304 are different number but she was thinking that the numbers are 340 and 340 not 304.
Well, check the picture below, that's a triangular prism
so.. if you notice, is really just 2 triangles and 3 rectangles stacked up to each other at the edges
so.. if you just find the area of the 3 rectangles, and the two triangles, sum all five areas up, and you're golden
in your picture, notice the tickmarks, that triangle has all sides equal to each other, so.. if one is 6 units, so are the other sides as well
now.. to get the area of a triangle is 1/2bh as you'd know... so.. what the dickens is the "h" or height of the triangle anyway, well

that's the altitude or height, you already know the base, notice the tickmark
so, get the area of those 2 triangles, and the 3 rectangles and sum them up, and that's the surface area of the triangular prism
The answer is <span>circumference</span>
Answer:
Oka
Step-by-step explanation:
Subtract or multiple
Answer:
If you take the 2 smallest sides and put it in the pythagreon theorem to get the other side length.
Step-by-step explanation:
So if you have a triangle with side lengths, 3, 4, and 5, you can use the exact equation below.

Because this is true, then the triangle does have a right angle.
