Answer:

34°

I hope its right...

Step-by-step explanation:

[2x + 6x + 2x+10]°=180°{since sum of all the angle of a triangle is 180°}

=>[10x + 10]°=180°

=>10x=180°-10°

=>x°=170°÷10°

=>x°=17°

∴2x[i.e∠A]=2×17°

=34°

Solution:

2x°+6x°+(2x+10)°=180°. [because sum of angle of a triangle is 180°]

Or,10x°+10°=180°

Or,x=180-10/10

Or,x=17°

Now,puttin' the value of x in A

= 2x°

= 2×17°

=34°

So,the measure of angle A is 34°.

Hope,itwill helpyaa:)
