Answer 2

Answer:

m=20, a+b+c=360, x=30, 43, 35.

Step-by-step explanation:

1.

Here,

70°+80°+(m+10°)=180°

=> m+160=180°

=> m=20°

2.

Here, a,b & c are a full angle.

So, a°+b°+c°=360°

3.

Ex.9--

2x°+5x°-30=180°

=>7x°=210°

=> x=30.

Ex.10--

x°+31+x°+20+x°=180°

=> 3x°= 129°

=> x=43

Ex.11--

4x°+x°+3x°+2x°+10°=360°

=> 10x°=350°

=> x=35
