Question

In a triangle,angle A is 20 more than angle B and angle B is 10 more than angle C,then what are angle A,B and C?​

Answer 1

Answer:

let angle C= x

then

B=x+10

A= x+30

we know that

sum of angels of triangle=180

then

x+x+10+x+30=180

3x=140

then x= 140/3

x= 46.67

then,

B= 56.66

A= 76.67

Answer 2

Step-by-step explanation:

Let angle B = 'x'

angle A = 'x+20'

Angle C= 'x-10'

in a triangle.....sum of all angles is 180...

so,

x + x +20 + x - 10 = 180

3x +10= 180

3x = 170

x = 170/3........

so, angle A = x +20

= (170/3)+20

= (170+60)/3

= 230/3

angle B = x

= 170/3

angle C = x-10

= (170/3)-10

= 140/3
