Question

find the value of x if the three angles of a triangle areew of measure 3x, 2x/2,5x/2

Answer 1

Answer:

20°

Step-by-step explanation:

3x+(2x/2)+(5x/2)=180°             (Angle sum property)

Now, we have to make the denominators equal.

So,    

6x/2+2x/2+5x/2=180°

Since the denominators are equal and all the numbers have same variable we can add them.

13x/2=180°

13x=180°*2

13x=360°

x=360°/3

x=20°
