Me i can't seem to get this one right

line ab contains points a(2, −4) and b(3, 1). line ef is perpendicular to line ab. which two points lie on line ef? e(2, −7) and f(5, −1) e(0, 2) and f(−1, 7) e(−3, 2) and f(7, 0) e(7, 4) and f(6, 1)

0.84 dang lotta people are looking for this lol or if you round up its 1 but the overall answer to that is 0.84

step-by-step explanation:

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.
