Aboat is 15 ft away from a point perpendicular to the shoreline. a person stands at a point down the shoreline so that a 65° angle is formed between the closest point to the boat, the person, and the boat. how far is the person from the boat? (what is the length d? ) label the sides of the triangle for opposite, hypotenuse, and adjacent to the 65° angle. use trig ratios to find side d. round your answer to the nearest tenth of a foot. show your work. ( i will mark brainliest and give ! )

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
