Question

Solve for x. The problem is in the picture!!

Answer 1

Explanation:

`x + 61 + 70 + 61 = 180(sum \: of \\ \: triangle) \\ \\ x + 192 = 180 \\ \\ x = 180 - 192 \\ \\ x = - 12`

# be careful#

Answer 2

According to the given Attachment

we know sum of all angles in a triangle is 180° .

• Sum of all angles in ∆ = 180°

On substituting the given value we obtain

➥ x + 61° + 70° + 61° = 180°

➥ x + 192° = 180°

➥ x = 180° - 192°

➥ x = -12°

So, the value of x is -12°
