Answer:
m<1 51°
m<2 34°
m<3 95°
m<4 38°
m<5 47°
m<6 74°
m<7 59°
m<1 there are 180° on a straight line. 180-129= 51°
m<2 there are 180° in a triangle. we have been given 95° and have just established that m<1 is 51° 180- 95- 51 = 34°
m<3 is a vertically opposite angle to the 95° given. therefore must = 95°
m<4 180° in a triangle. have just established m<3 as 95° have been given 47°. 180 - 95 - 47 = 38°
m<5 is vertically opposite to the 47° given so therefore = 47°
m<7 180° on a straight line 180 - 121 = 59°
m<6 180° in a triangle have previously established that m<5 = 47° and m<7 = 59°
180 - 47 - 59 = 74°
hope that helps xx
