Question

IF A TRIANGLE HAVE GIVEN ANGLE A=80 DEGREE AND TWO ANGLES ARE EQUAL.THEN FIND THE BOTH THE ANGLES​

Answer 1

ANSWER-

□/_ A =80°✔✔

□/_ B =50°✔✔

□/_ C =50°✔✔

Step-by-step explanation:

YOUR QUESTION IS THAT

□angle A=80°✔✔

○angle B = angle C=X°✔✔

WE KNOW THAT THE SUM OF ALL ANGLES OF A TRIANGLE IS 180° DEGREE

WE KNOW THAT THE SUM OF ALL ANGLES OF A TRIANGLE IS 180° DEGREESO,

/_A+/_B+/_C=180°

80°+X+X=180°

2X=100°

X=50°(each)✔✔

Answer 2

SOLUTION

Given,

Angle A= 80°

Two angle are equal

Let the angle be x

We know that sum of triangle = 180°

=) x° + x° +80° = 180°

=) 2x° +80° = 180°

=) 2x° = 180° - 80°

=) 2x°= 100°

=) x= 100/2

=) x=50°

so,

Angle A = 80°

Angle B= 50°

Angle C = 50°
