Ya I’m pretty sure it’s 125
So when you change the mixed numbers into improper fractions, they become 85/4 and 74/4. Your new problem is 85/4-74/4. Basically 85-74. That equals 9. So the improper fraction answer is 9/4. We now make that back into a mixed number, creating 2 1/4, or A.
The angles all add up to 180
42 + 42 + x = 180
84 + x = 180
x = 96
x = the third angle
A,C, and D! x factors should always have a number next to them to show through tape diagrams , those without them are automatically eliminated , the rest have number answers and are correct
