What is the value of x in the diagram?

Step-by-step explanation:

here 50 is hypotenuse as it is opposite of 90 degree.

x and x + 10 are the two other smaller sides of a right angled triangle respectively.

using pythagoras theorem,

a^2 + b^2 = c^2

x^2 + (x + 10)^2 = 50^2

x^2 + x^2 + 20x + 100 = 2500

2x^2 + 20x = 2500 - 100

2(x^2 + 10x) = 2400

x^2 + 10x = 2400/2

x^2 + 10x = 1200

x^2 = 1200 - 10x

x =

x = 30

Step-by-step explanation:

Using Pythagoras Theorem:

Since x is the measurement of a side, it can't be negative. Therefore x = 30
