Question

find the value of the unknown x in the diagram.​

Answer 1

Answer:

sum at all angles in a triangle is 180 so angleA+B+C = 180

B+C=50+60=110

A=180-110

A=70

Answer 2

Answer :-

Given :-

• Two angles of a triangle are 50° and 60°.

To find :-

• The value of the unknown x.

Step-by-step explanation :-

A triangle has 3 sides.

The sum of all the angles in a triangle = 180°.

Here, we know that the two angles of the triangle are 50° and 60°. We have to find the third angle.

Therefore, we get :-

$\sf 50° + 60° + x = 180°$

$\sf 110° + x = 180°$

$\sf \: x = 180° - 110°$

$\sf \: x = 70°.$

Thus, the unknown x in the given diagram is 70°.
