Answers to questions A and B

A. m(arc BC) = 16°

B. m(arc BAC) = 344°

Step-by-step explanation:

From the picture attached,

AB is the diameter of the circle.

Since, measure of an arc is always same as the central angle of arc.

Therefore, m(arc AC) = m(∠ADC) = 164°

m(arc AB) = 180°

m(arc BC) = 360° - m(arc AB) + m(arc AC)

                = 360° - (180° + 164°)

                = 360° - 344°

                = 16°

m(arc BAC) = m(arc AB) + m(arc AC)

                   = 180° + 164°

                   = 344°

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!
