Question

Find the measure of angle x. Round your answer to the nearest hundredth. (please type the numerical answer only)

A right triangle is shown with one leg measuring 12 and the hypotenuse is labeled 13. An angle that is not 90 degrees is marked x.

Answer 1

i think the answer is 0.0189
but i really could use some help please.

Answer 6

angles in a triangle add up to 180° so you see your ans is off

cos (x) = adjacent / hypotenuse= 12/13
look up the inverse cos to get the angle

Answer 7

another way of doing this is to use pythagorean theorem and find the length of the other side
sq rt (13^2 - 12^2) = 5 then applying sin ratios knowing the sin of 90° = 1
13/1 = 5/sin x solve for sin x then look up the inverse sin to get the measure of the angle

Answer 8

what was the answer?
I am done but I would still like to know what the correct answer was. I was wrong

Answer 9

this is what I had above
cos (x) = adjacent / hypotenuse= 12/13
look up the inverse cos to get the angle

cos x = 12/13 = 0.92307
cos(-1) x on the calculator gives 22.619
to the nearest hundredth means to 2 decimal places
I got 22.62°
is that what you are saying you got wrong?

Answer 10

do you want to show me what you did?
