Question

one of the anglesof atriangle has measure 80°and the other two angles are equal​

Answer 1

Answer:

Step-by-step explanation:As we know the sum of angles of a triangle is 180. If 1 angle is 80 and other two angles are equal . Then the other two angles are 50 and 50.

Let these angles be x . So the equation will be

x+x+80=180

2x=180-80

x=100÷2

x=50

Answer 2

Answer:

If another two angles=X+x

Step-by-step explanation:

$x + x + 80 = 180$

sum of three angles in triangle is 180 degrees..

$2x + 80 = 180$

$2x = 180 - 80$

$2x = 100$

$x = 50$

one angle measure is 50

another angle measure is 50+50=100
