Question

Find the value of x. A. 18 B. 22 C. 24 D. 28

Answer 1

A. 18 is correct it smaller

Answer 2

Answer:

The correct answer option is A. 18.

Step-by-step explanation:

We have a right angled triangle with the complete values of two sides: the perpendicular and the base with side lengths 40 and 30 respectively.

We can use the Pythagoras Theorem to find the hypotenuse.

Assuming the hypotenuse to be A:

$A^2 = 30^2+40^2$

$A^2= 900+1600$

$A^2=2500$

$\sqrt{A^2} = \sqrt{2500}$

$A=50$

To find x, we will subtract 32 from the length of hypotenuse:

$x = 50-32=18$

Therefore, the value of x = 18.
