Question

The three angles of a triangle are x, x+10 , x +20 in degrees. The smallest angle will be​

Answer 1

Answer:

x+x+10+x+20=180

3x+30=180

3x=150

x=50

x+10=60

x+20=70

so x is smallest angle

Answer 2

Answer:

The smallest angle of triangle is 20°.

Step-by-step explanation:

The sum of all angles of triangle is 180°. So x, x+10, x+20 are the measures of that angles.

So x+x+10+x+20=180.

Then 3x+30=180.

3x= 180/3

3x= 60

So x= 60/3

x= 20

So the smallest angle is 20°.
