Answer:
1. x = 10
(triangle has equal side lengths)
2. x = the same number inside the triangle
(is that a 40 or 80?)
3. x = 34
(is that a 34?)
4. x = the number shown on the other side of the triangle
(is that a 55?)
5. if the given number is 8 then x = 11
(11-3=8)
6. x = 11
(2x-15=7)
7. x = 5
(65+5=70)
8. x = 10
(5x-10=40)
9. m<2 = 9
(7x-3=60)
10. m<2 = 8
(x+72=80)
hope this helps!
