Answer:
a
Step-by-step explanation:
the other angles do not open past an L shaped to be larger than 90, so c and d are out. For choice b, the b corner doesn't make an L shape either so it is not 90.
Answer:
yes
Step-by-step explanation:
Using the Pythagorean Theorem, considering that the sum of the squares of the lengths of the two smaller sides is equals to the square of the length of the greater side, the triangle is a right triangle.
Pythagorean Theorem:
The Pythagorean Theorem states that for a right triangle, the sum of the squares of the lengths of the two smaller sides is equals to the square of the length of the greater side.
so it is a right triangle.
the answer is 1 and 4
Start by subtracting, so on #1 subtract 5-8, 8-11, 11-14
then go up to x, -2--1, -1-0, 0-1
I did the same thing and got 6 as well
