Question

One method you can use to determine whether a triangle is a right triangle, given three side
lengths, is to apply the Converse of the Pythagorean Theorem. Alternately, you can use
trigonometric ratios. Show that the triangle in the diagram is a right triangle by using
trigonometric ratios. (Be sure to show all work and/or reasoning.)
Hint: Use the Inverse Trigonometric Functions to solve for mB and mC and then use the Triangle Sum
Theorem
Is this correct?
I did A^2+B^2=C^2
33^2+56^2=65^2
1,089+3,136=4,225
4,225=4,225
So yes it is indeed a right triangle

Answer 1

yep :-)
both sides are equal gO_Od to go!

Answer 2

Thank you!

Answer 3

what diagram ?

Answer 4

A Triangle

Answer 5

okay you didn't post that :-)

Answer 6

sure :-)

Answer 7

alright there is *inverse trig * so i just wanted to make sure :-)

Answer 8

btw there is a attach file button(blue one) you can attach file :-)
gO_Od luck!

Answer 10

Thank you ya there is a trig function that's why i don't know if i did the right formula?
