Answer:

4

Step-by-step explanation:

use the Pythagoras' theorem

formula for an ABC triangle( right angled)

AB is height

BC is hypotenuse

CA is length

$BC^{2}$ = $AB^{2}$ + $CA^{2}$

in your case

AB is 7

BC is 8

CA is unknown so we write x

$8^{2}$ = $7^{2}$ + $x^{2}$

64=49+ $x^{2}$

64-49= $x^{2}$

15= $x^{2}$

$\sqrt{15}$ =x

3.87=x

4=x
