How can I improve my math? How can I get better grades and scores in competitions like AMC 8, 10, 12, and MATHCOUNTS? I get low scores and it's really annoying. I've taken so many, I'm starting to feel mad at myself and feel stupid and dumb. How can I make sure I don't get bad grades?

1. You r not dumb or stupid ur just having a hard time

2.u could get a tutor or someone who can help u understand differnet things and improve your grade

3.You could pratice/study more

4.Ask your teacher for help if u don't understand something

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.

the answer is d

hope this
