What is the measure of angle b in degrees?

An outside angle is the sum of the two opposite inside angles.

The outside angle given as 112 is the sum of A + 51, so A = 61

A and B are supplementary, so they need to sum to 180.

B = 180 - 61

B = 119

2/7

Step-by-step explanation:

There are seven tiles. You want to 5 and the 6 so the fraction is 2/7. That's the chance that you have to pull both numbers.
