Answer:
4. m<3 = 120
5. m<4 = 13
6. m<2 = 70
7. m<1 = 115
Explanation:
4. m<3 = 120, this is because it is the same as m<1 due to vertical (congruent) angles
5. m<4 = 13, this is because it is the same as m<2 due to vertical (congruent) angles
6. m<2 = 70, this is because m<2 and m<3 are supplementary (adding up to 180) so we would subtract 180 - 110 (aka m<3) = 70 (aka m<2)
7. m<1 = 115, this is because m<1 and m<4 are supplementary (adding up to 180) so we would subtract 180 - 65 (aka m<4) = 115 (aka m<1)
