How do I do this ? This is mad confusing lol

2=137⁰

3=31⁰

1=47⁰

Step-by-step explanation:

2 is on a straight line with 43 and a straight line is 180 degrees so 180-43=137

A triangle has 180 degrees and we figured out 2 so 137+12 then subtract from 180 equals 31 degrees

3. The box in the triangle represents 90⁰ so 43 + 90 then subtract from 180 equals 47

u dumb boi

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.
