Answer 1

$\huge\tt{\bold{\purple{\underbrace{\red{\mathfrak{Answer:}}}}}}$

Here, we know that (2x + 10) + (6x+10) = 180°

As, they are co-interior angles.

⠀

So,

(2x + 10) + (6x+10) = 180°

2x + 10 + 6x + 10 = 180°

8x + 20 = 180°

8x = 160°

x = 160°/8

x = 20°

⠀

⠀

Answer:- x = 20°

Answer 2

Answer:

Sum of interior angle is 180⁰

2x+10 + 6x+10 = 180⁰

8x+20=180⁰

8x= 180⁰ - 20 = 160 ⁰

8x= 160⁰

x= 160⁰/ 8

x= 20⁰
