Question

If two angles of a triangle are equal and the third angle is 50 degree , find the two angles.

A) 65,65
B) 55,55
C) 75,75

Answer 1

while 2 angles are equal

let be x one angle

now the sum of three angles in triangle is 180*

then

x+x+50=180

2x+50=180

2x=180-50

2x=130

x=130/2

x=65

now two angle of triangle are : 65,65

Answer 2

Answer:

A -/ 65 , 65

========================

• Let , one of the two equal angles of the triangle be X .

• Let , one of the two equal angles of the triangle be X Hence , the sum of both the angles will be = X + X =2 X.

• Let , one of the two equal angles of the triangle be X Hence , the sum of both the angles will be = X + X =2 XThe measure of the the third angle is 50 ° .

• Let , one of the two equal angles of the triangle be X Hence , the sum of both the angles will be = X + X =2 XThe measure of the the third angle is 50 ° We know that Sum of all the angles in a triangle is 180 ° .

• Let , one of the two equal angles of the triangle be X Hence , the sum of both the angles will be = X + X =2 XThe measure of the the third angle is 50 ° We know that Sum of all the angles in a triangle is 180 ° .

• Hence , According to the question /-

2 X + 50 = 180 °

or, 2 X = 180 - 50 °

or, 2X = 130 °

or, X = 130 ÷ 2

or, X = 65 °

Therefore , the measure of the two angles are 65 ° .
