Given a right triangle having an acute angle 5' of 12and an adjacent side of length 2 LII], find the measurement of the other angle and the other sides. Show work. Be sure to clearly lemon which ofyour answers is the length ofthe side opposite to I9 and which is the length of the hypotenuse, as well as stating the measure of the other acute angle. Report the lengths rounded to one decimal place. 5. Use a sum or a diEerenee identity to nd the exact value of sin {235\"}. Show work. E. A person is sitting on the ground between the Home and Baker buildings. The person is 43 feet om the Acme building. The Baker building is 4?.2 feet tall. From the person's point ofview, the angle of elevation to the top of the Acme building is 3'3\" and the angle of elevation to the top of Baker building is 454]\".
