The value of b when solving the equation 2(b+12)=16 is

b=2

Step-by-step explanation:

You just have to add 12 and 2 then subtract that by 16.

D) -4

Step-by-step explanation:

I looked up what 2 (b + 12) = 16 and the answer is -4 and plus I know it's 100% right because I am on this question right now on Edulastic.

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

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
