If θis an angle in Quadrant III, which trig ratio(s) will be positive? A. θsin

B. θcos

C. θtan

D. sin θ , cos θ , tan θ

C

Step-by-step explanation:

Here, we want to select the the trigonometric ratio that is positive quadrant iii

The trigonometric ratio positive in quadrant iii is the tangent

This is the ratio of the opposite to the adjacent and it is usually abbreviated as tan theta

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.
