Question

calculate ‘X’. please help me​

Answer 1

Answer:

x = 9 is the only correct answer

Answer 2

$\huge{\boxed{\boxed{\underline{\rm{\purple{Answer}}}}}}$

Step-by-step explanation:

In the figure CB²= 15² - 12²( pythagoras property.)

Base² = Hypotenuse² - Altitude²

CB² = 15² - 12²

CB² = 225 - 144

CB² = 81

CB = √81

CB = 9

DC² = 15² - 12²(pythagoras property)

DC² = 225 - 144

DC² = 81

DC = √81

DC = 9

We know that x = BC + CD

So x = 9 + 9 = 18
