Question

The measures of angles of a triangle are X°, ( X – 10)°, ( X –20)°,Find the measure of each angle.​

Answer 1

Step-by-step explanation:

sum of angles in a triangle=180°

x+x-10+x-20 =180

3x-30=180

3x=180+30

3x=210

x=210/3

therefore,

*x=70°

*x-10=70-10=60°

*x-20=70-20=50°

Answer 2

Answer:

x = 70

( x - 10 ) = 60

( x - 20 ) = 50

Step-by-step explanation:

So we wil do this question using angle sum property of triangle

x + ( x - 10 ) + ( x - 20 ) = 180

3x - 30 = 180

3x = 210

x = 70

( x - 10 ) = 60

( x - 20 ) = 50

these are all the angles of the triangle

thank you :-)
