Question

one of the angels of a triangle is 120° and the other two angles are equal. find the measure of each of the equal angel​

Answer 1

Answer:

the other 2 angles are 30⁰ as the sum of all the angles of a triangle are 180⁰

Answer 2

Answer:

• The measures of each of the angels is 30°

Step-by-step explanation:

Given :

• One of the angel of triangle is 120°

• The other two angels are equal

To Find :

The measure of two equal angles

Solution :

• Let the other two angels be x

Sum of all angles of a triangle is 180°

120° + x + x = 180°

120° + 2x = 180°

2x = 180° - 120°

2x = 60°

$\boxed{\pink{x = 30°}}$

$\small\underbrace\mathrm\red{Verification\::-}$

120° + 30° + 30° = 180°

120° + 60° = 180°

180° = 180°

LHS = RHS

Hence proved
