Answer:
42 degrees
Explanation:
Since side AB is congruent, or equal, to side AC, this means that angles ABC and ACB are equal also.
If m∡ACB equals 69 degrees then m∡ABC equals 69 degrees.
69 + 69 = 138
There are a total of 180 degrees in a triangle which means that m∡CAB is equal to 180 minus 138, or 42 degrees.
