Answer:
answer is 17.5
Step-by-step explanation:
use formula a^2 + b^2 = c^2 (letters represent each side of the triangle)
9^2 + 15^2 = 306
306 = x^2. find the square root of 306 to find x
√306 = 17.4928557
rounded it to the nearest 10th
17.5
Answer:
Yes, it does.
Step-by-step explanation:
Every regular shaped figure will have rotational symmetry, since they are built with identical segments all around.
To find the answer, ask yourself « If I rotate the shape, is there a time where I’ll find the exact same shape again with a different angle? »
So, a square has rotational symmetry, but not a rectangle.
A equilateral triangle has rotational symmetry, but not any other type of triangle.
The the answer is A you welcome
