Answer:
See below
Step-by-step explanation:
(7x +3) is the same as angle opposite B
So 7x+3 will equal 103 degrees.
To figure out angle ACB we just take a straight line (180 degrees) and minue 103, which gives us 77 degrees
ACB = 77 degrees
Now we will just isolate x so we can figure out it's value for angle CAB
7x = 103 - 3
7x = 100
x = 100/7
x = roughly 14.3
CAB = 3x - 10 = (14.3 * 3) - 10
= 43 - 10
CAB = 33 degrees
