Question

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

Answer 1

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.
