Question

If the m<7 =60 find m<2
(Please help and explain)

Answer 1

we have m(7)= 60 , which mean that the opposite angle is the same equal 60 , m(6)=60 . then we have to get angle 4 which is 180-60 = 120 ( we know that two angles making U shape are 180) then we get m<4 =120 . angle 4 + angle 2 are = 180 (making straight line) ,180-120=60 angle 2 = 60
