2. What is the value of x if the angles<br> within a triangle are 2x +1, 7x-2 and 3x<br> +5?

noname [10]

Answer:

$x=14.67\\$ °

Step-by-step explanation:

The sum of all the three angles of any triangle is 180°

Putting sum of all the angles given equals to 180°

$(2x+1)+(7x-2)+(3x+5)=$ $180$ °

$2x+7x+3x+1-2+5=180$ °

$12x+4=180$ °

$x=\frac{180-4}{12}$

$x=14.67\\$ °

The value of the x is found on solving the given angles of the triangles.
