Question

. Yo. Find his gan The angles of a triangle are (2x)°, (3x+5)° and (4x -14)°. Find the x. and also measure of each angle of triangle​

Answer 1

Answer:

We know

Sum of all interior angles of a triangle are supplementary, that is 180°

therefore

here,the angles are

2x,3x+5,4x-14

substituting the values

2x+3x+5+4x-14=180

9x-9=180

9x=180+9=189

x=189÷9

x=21

therefore the angles are

2x=2×21=42°

3x+5=3×21+5=68°

4x-14=4×21-14=70°

Let's check whether it's correct or not

2x+3x+5+4x-14=180

42+68+70=180

180=180

L.H.S=R.H.S

hence verified

2x,3x+5,4x-14

substituting the values

9x=180+9=189

x=189÷9

x=21

therefore the angles are

2x=2×21=42°

3x+5=3×21+5=68°

4x-14=4×21-14=70°

Let's check whether it's correct or not

2x+3x+5+4x-14=180

42+68+70=180

180=180

L.H.S=R.H.S

hence verified
