Question

the sum of two angles of the triangle is 80degree difference is 20degree find all the timeangles of triangle​

Answer 1

Answer:

let two angle be X and Y

X+Y=80

X-Y=20

we get 2X=100

X=50

by putting value in one of the equation

we get

Y=30

let third angle be Z

so sum of angles of traingle is 180°

X+Y+Z =180°

50+30+Z=180°

80+Z=180

Z=100

so angles are

X=50

Y=30

Z=100

thank you

Answer 2

Answer:

here is your answer ☺☺☺

let one angle be X

let another angle be Y

therefore X+Y=80___(1

X-Y=20___(2

add 1and 2

2X=100

X=50

thusY=30

therefore anther angle is 100
