Question

The angles of a triangle are(x+10),(2x-30) and (x) find the value of x

Answer 1

Answer:

The value of x is 50.

Step-by-step explanation:

Given : The angles of a triangle are (x+10), (2x-30) and (x).

To find : The value of x ?

Solution :

The angles of a triangle are (x+10), (2x-30) and (x).

The sum of angles of triangles are 180°.

$x+10+2x-30+x=180$

$4x-20=180$

$4x=180+20$

$4x=200$

$x=\frac{200}{4}$

$x=50$

The value of x is 50.

Answer 2

Answer:

Value of x = 50

Step-by-step explanation:

The angles of a triangle are (x+10), (2x-30) and x.

Sum of three angles = 180°

/* Angle sum property */

=> ( x + 10 ) + ( 2x - 30 ) + x = 180°

=> x + 10 + 2x - 30 + x = 180°

=> 4x - 20 = 180°

=> 4x = 180 + 20

=> 4x = 200

/* Divide both sides by 4, we get

=> x = 50

Therefore,

Value of x = 50
