Question

Find the value of the unknown x in the following diagrams:​

Answer 1

Answer:

The sum of all 3 interior angles in a triangle is 180∘.

So, 50 + 60 + x = 180 degree

110 + x = 180 degree

x = 180 - 110 = 70 degree

Answer 2

$\huge\underline\mathrm{SOLUTION:-}$

We know that,

• The sum of all the interior angles of a triangle is 180°.

Then:

= ∠BAC + ∠ABC + ∠BCA = 180°

= x + 50° + 60° = 180°

= x + 110° = 180°

By transposing 110° from LHS to RHS it becomes - 110°

x = 180° - 110°

x = 70°

• Hence, x = 70°
