Question

If g = 26.4 and F = 35° find h. Round to the nearest tenth.

Answer 1

So you know what g (the hypotenuse) is and you want to find h (the adjacent side). So which trig function relates adjacent to hypotenuse? That should do it. :)

Answer 2

I know I use cos but I don't know how to put this on the calculator

Answer 3

OK, so you just need to take the cos of the angle you gave:

cos(35) = adj/hypo

Then you can solve for the adj once you have a decimal approximation for cos(35) on your calc.

Answer 4

So I got the answer -.9, honestly I have no idea what to do from there :l

Answer 5

is your calculator in radians mode? You shouldn't get -0.9...

Answer 6

Yeah, Idk how to turn it off.

Answer 7

are you using a TI calculator or what brand do you have?

Answer 8

TI-84 Plus

Answer 9

Hit the MODE button, then use the arrow keys to highlight degrees, then hit enter.

Answer 10

to get out of the MODE screen hit 2nd then MODE again.

Answer 11

okai i got .819 now

Answer 12

good.

Answer 13

so you now know that 0.819 = adj / 26.4 since the hypotenuse = g = 26.4

Answer 14

Yes

Answer 15

solve for adj by multiplying both sides by 26.4 and round your answer and you are done

Answer 16

YAY! Thank you!
