Question

Given triangle GHJ and side g = 6; side h = 2. Find the measurement of angle H if angle J is a right angle.

Answer 1

Can you find the tan of angle H from the diagram?

Answer 2

Hi and thanks.

Answer 3

No I can't.

Answer 4

\[\tan H=\frac{2}{6}\]
Therefore H is given by\[H=\tan^{-1} \frac{2}{6}\]

Answer 5

Ok ..

Answer 6

Can you use a calculator to find the value of angle H ?

Answer 7

Wait I will

Answer 8

Is Side GH the hypotenuse?

Answer 9

Yes. But you do not need to know the length of the hypotenuse to find angle H.

Answer 10

We aren't using the pythagorean theorem?

Answer 11

The pythagorean theorem is not relevant to this question.

Answer 12

How do I find the value?

Answer 13

Make sure the calculator is set to degrees, then calculate the value of\[\tan^{-1} (\frac{2}{6})\]

Answer 14

my calculator doesn't have that
