Answer 2

$question$

In figure 10,l ll m and p ll q. Find the measure of angle a ,angle b, angle c and angle d.

$answer$

∆a = 55° [opposite angles]

l ll m and p cuts it

so,Lb+La=180°

Lb+55°=180°

Lb=125°

p ll 2 and m cuts it

so,La+Ld=180°

55°+Ld=180°

Ld=125°

p ll 2 and L cuts it ,

so, cb + Lc =180°

125° + Lc = 180°

Lc= 55°
