Answer:
3 and 7
2 and 6
4 and 8
1 and 8
Step-by-step explanation:
The last two are correct: “If I know the measures of Angles C and B, I can find the angles of A and D.” and “If I know the measure of angle A, I can find the measure of angle D by subtracting from 180”
Hope that helps: )
All 3 angles of a triangle add up too 180, so 80+55= 135, 180-135 is 45, so the value of x is 45
