Question

Find the value of x if the three angles of a triangle are 3x,x/2,5x/2

Answer 1

Answer:

30 degrees

Step-by-step explanation:

3x +x/2 +5x/2 =180 (angle sum property of triangle)

6x+x+5x=360 (taking lcm and cross multiplying )

12x =360

x=30

hope this helps you

Answer 2

Answer:

x=30

Step-by-step explanation:

angle 1=3x

angle 2=x/2

angle 3= 5x/2

sum of all the angles in a triangle add up to 180

therefore;

3x + x/2 + 5x/2 = 180

(6x + x + 5x)/2 = 180

12x/2 = 180

6x = 180

x = 180/6

x = 30
