Question

(x + 40)
(3x)
What is value of x

Answer 1

Explanation:

multiply both sides by 3x

3[x+40]x[x+40]

3x +120+x(square)+40x

43x+120+x(square)

quadractic equation

x(square)+43x+120

(x+40x+)(3x+120)

x(1+40)3(1+40)

x:3 or 40

Answer 2

The value of x in the diagram is 20.

From the diagram given :

• x + 40 = 3x (opposite angles)

Now we have;

x + 40 = 3x

x - 3x = -40

-2x = -40

x = 40/2

x = 20

The value of x is 20.
