Arc qvt measures 156

which statement must be true?

r

angles qrt and qst both measure 78°

angles qrt and qst both measure 156

angle qrt measures 78° and angle qst measures

102

angle qrt measures 156° and angle qst measures

24

Angles QRT and QST both measure 78 degrees

Step-by-step explanation:

We are given that

Measure of arc QVT=

We know that

Central angle is equal to measure of intercepted arc

Inscribed angle formed by same arc are equal

Inscribed angle is equal to half of the central angle.

Hence, measures of angle QRT and angle QST are equal.

Therefore, option A is true.

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
