Question

Measures of two angles of a triangle are the same and the third angle is 80ᵒ. Find the measure of each angles.​

Answer 1

Answer:

lemma-the sum of 3 angles in triangles =180°

lets say we have been given three angles a,a,80°

since two angles are equal thats why i have taken a, a

according to the upper lemma a+a+80°=180°

2a=100°

a=50°

so the three angles are 50°, 50°, 80°

Step-by-step explanation:

so the three angles are 50°, 50°, 80°

Answer 2

Answer:

2X = 100

1X = 50

50 + 50 + 80 = 180.

Step-by-step explanation:

Given : Measures of two angles of a triangle are the same and the third angle is 80º.

To Find:

• Measure of each angle of the Triangle.

Solution :

→ Let the same angle be = X

As we know that Sum of all angles of a Triangle is 180°.

So, x+x+80°

→ 2x +80° = 180°

→ 2x = 180° - 80°

→ 2x = 100°X

→ x = 50°

So,

The Measure of two same angles is 50°.

VERIFICATION :

X+X+80° - 180°

50+50 +80° = 180°

→ 100° +80° 180°

→ 180° = 180°
