Question

Please answer the questions given above.


​

Answer 1

Answer:

a=25°  and x=20°

Step-by-step explanation:

1.

∠1= (30-a)°

∠2=(125+2a)°

They're supplements, i.e.

∠1 + ∠2 = 180°  

(30-a)° + (125+2a)° = 180°  

30-a+125+2a=180

a=180-125-30

a=25°

2.

Sum of all angles in a circle is 360°

Also, vertically opposite angles are equal.

So,

2(90+x+3x+10)=360        

(in the fig., notice there are 3 pairs of v.o.a. so we multiply it by 2)

100+4x=180

4x=80

x=20°
