Question

Use this image to answer questions 5 & 6. < BAC = 44° and < BCD = 131°

Answer 1

There are 2 angle measurements not identified.

Angle ACB and angle ABC.

To find angle ACB you need to know that a straight line is 180 degrees, so if the angle to the right is 131, the angle to the left (Angle ACB) must be 49 degrees.

To find angle ABC, you need to know that the sum of all 3 angles in a triangle equal 180 degrees, so 180 - (49 + 44) = 87 degrees.  Angle ABC is 87 degrees.
