Construction workers have began to dig a hole for a swimming pool. They want to check that the angle they have dug is 90°. They measure the diagonal as shown to be 9.5 m. Is the angle 90°?
Explain your reasoning!
So here are my answers.
I calculated the side lengths by squaring the numbers 6 and 8 and multiplying them by the same number I got 100.
I times 6x6=36 and 8x8=64 although adding them made it 100°. So
√100 = 10m
Another reason I have is that the angle is not a(n) right angle because since its not a perfect square because the diagonal should be 10m to be right angled. Also if it was gonna be a perfect square it should have been a 7x7 square but anyway since this question is easy comment if you want but yeah!
PLEASE COMMENT!!!!!!!!!! NOW hehe!!!!!!!!!!!!!!!
