Answer: 56 degrees

Erase the word "degrees" and enter the number only if necessary. Or use the degree symbol instead.

========================================================

Step-by-step explanation:

The single tickmarks on the top left and top right sides tell us those segments are equal in length. This triangle is isosceles.

Any isosceles triangle has congruent base angles (in this case angles A and C). So we can say A = C. These congruent base angles are opposite the congruent sides.

-------

The three angles of any triangle add to 180

A+B+C = 180

A+68+A = 180

2A+68 = 180

2A = 180-68

2A = 112

A = 112/2

A = 56

Therefore, angles BAC and BCA are 56 degrees each.
