Question

in a triangle the sum of two angle is equal to the third angle if the difference between them is 50 degree find the angle​

Answer 1

Answer:

I have not read the question carefully

Answer 2

Answer:

Step-by-step explanation:let the angles be x , y and z.

We know ,

sum of angles of a triangle is equal to 180°.

so,

(x+y+z=180° ) equation -1

given that

x+y = z

and

(x-y =50) 2nd eq.

so

x=50 + y

now put value of x in 2nd eq.

we get,

50+y+y=z

50+2y = z

now ,

x + y+ z = 180°

z+z=180° (from eq 1)

2z=180°

z=180÷2

{z=90°}

now,

x+y = 90° (from eq. 1)

50+y+y= 90 (x=50+y)

50+2y=90

2y=90-50

2y=40

y=40÷2

y=20

now,

x+y =z

x+y=90

x+20=90

x=90-20

x=70

so we get

x=70

y=20

and z = 90
