Answer:
25.37∘ or to the nearest degree: 25∘
Explanation:
Since this is a right triangle, we are able to use the
tan,sin,and cos functions.
We know the lengths of the opposite side from ∠H and the hypotenuse, so we will use the sin function. sin∠H=opposite hypotenuse → sin∠ W
=37 Using your calculator, find the value of 37. The equation should now look like this: sin∠H= 0.42857...
Without clearing the calculator (a.k.a. leaving what is on the screen there) hit 2nd and then hit sin. This will show you the measure of ∠W. (You may not have a 2nd button in which case use sin−1.)∠H=25.37→25∘
Here are a couple things to remember when you see questions like this:
Determine which side lengths you know so that you can decide which function to use (tan,sin,cos)
When you have the form like the one that we had in this question (
sin∠H=0.42857...) remember to hit 2nd
and then the function. Or, depending on your calculator, you should use
sin−1,cos−1,tan−1 instead.
Hope this helps sorry if it wrong but I am 99.99% sure its right I am in high school and did that to I have bin home schooled and done that same school
