Question

If in a triangle two angles are equal and the third angle is 120degrees , what are the equal angles

Answer 1

Step-by-step explanation:

Let take equal angles as X

$x + x + 120 = 180$

$2x = 60$

$x = 30$

GIVEN THAT :-

$&#10146$ In a triangle two angle are equal and third angle is 120°.

SOLUTIONS:-

$&#10146$ Let each of equal two angle is x° .

In a triangle the sum of all three angle is 180°

$\implies \: \: x + x + 120 = 180 \\ \\ \implies \: \: 2x = 180 - 120 \: \: \: \: \: \\ \\ \implies \: \: x = \frac{\cancel{60}}{\cancel{2}} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \implies \: \: x = 30 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$

• So the equal angles is 30°.
