Answer 2

there are many ways
<5+<6+<7 = 180

Answer 3

∠ 7 and ∠ 3 are alternate interior angles.

m∠5 + m∠6 + m∠7 = 180º

given m∠5 and m∠6, m∠7 = ?

m ∠3 = 80º

Answer 4

and <7 = < 3 (alternate interior angle)

Answer 5

Ohh okay. Thank you. My book didn't explain it very well.

Answer 6

another way is u see m<5 = m< 2
and m<2 + m<3 +m<6 = 180
sum of all angles of a triangle is 180
