WILL MARK BRAINLIEST! Elevation questions:
1. how much higher is 500 than -400 m
2. how much higher is -200 m than 450 m

900 and 650

Step-by-step explanation: so because 400 is negative, it would take 400 to get to 0 and 500 more to get to 500 so 900 for 1. And same thing for the second one, -200 plus 200 is 0 plus 450, it’s 650

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.

alright well the answers to your question is
