Question

The sum of angles of a triangle is 180 degree. If the three angles are (2x+15)°. 75º. (x + 20°, then find
value of x.​

Answer 1

Answer:

(2x+15) +75+(x+20)=180

2x+x+15+75+20=180

3x+110 =180

180-110 =3x

70 =3x

x= 70/3

=23.33

Answer 2

Answer:

The value of x is 70/3

Step-by-step explanation:

as the expression of all the 3 angles are given ,

form an other  expression by adding all the expressions of the angles,

Then solve the equation with the RHS as 180.

Then you'll be able to find the value of X that is : 70/3.
