The sail of a boat is in the shape of a right triangle, as shown below:
the sail of a boat is a right triangle with an acute angle at the tip equal to 50 degrees and the side of the sail which is the
which expression shows the length, in meters, of the base of the sail? a. 7 cosec 50°
b. 7 divided by sec 50 degrees
c. 7 divided by cosec 50 degrees
d. 7 cot 50°

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.
