Question

in a triangle,one angle is 100°and the other two angles are such that one is lesser in measure by 20 than the other.what are the measures of these two angles.​

Answer 1

Answer:

50°, 30°

Step-by-step explanation:

x + (x - 20) + 100 = 180°

2x = 100 => x = 50 °

& x - 20 = 50 - 20 = 30°

Answer 2

Answer:

other two ∠ are 30°, 50°.

Step-by-step explanation:

int. angle of△:

(n-2)180

(3-1)180

= 18O°

let one be x and other be x + 20.

x + x + 20 + 100 = 180

120 + 2x = 180

x = 30°.

x + 20 = 50.
