Question

The angles of a triangle are $(2x+5{)}^{\circ },(x+20{)}^{\circ }and(2x-10{)}^{\circ }$. Find then value of 'x' is $34$

• A. True
• B. False

Answer 1

The correct option is B False

The angles of the triangle are, $(2x+5),(x+20),(2x-10)$
Now, the sum of angles = 180
$2x+5+x+20+2x-10=180$
$5x+15=180$
$5x=165$
$x=33$
Thus, the measure of angles = ${71}^{\circ },{53}^{\circ },{56}^{\circ }$
