Question 1063506
If you want to prove that tan 47.3 = 13/15, draw a right angle, one side measuring 13 and the other measuring 15 then connect the end points of the two sides to form the hypotenuse. Label your drawing. Remember that tan 47.3 is opposite side divided by adjacent side. Then use a protractor to measure the angle if it is 47.3. I did it. tan 47.3 is not equal to 13/15.

Right Triangle 5-12-13 has no 45 degree angle.

Using of a 45-45-90 is not accurate, better if you have a protractor.

Yes it is true that tan 47.3 = 13/12.

cheers mate!
