Trigonometry 11 Word Problem Suppose Romeo is serenading Juliet while she is standing on her 3rd floor balcony. The balcony is 15 m in height above the ground. Juliet sees Romeo at an angle of depression of 25°. Paris, Juliet's other suitor, is observing the situation and sees Juliet on the balcony at an angle of elevation of 18°. If distance between Romeo and Paris is 66.5 m, determine the angle between two sightlines to the nearest degree. Include a well-labelled diagram.

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle

Iagree that is the answer to the question
