Question

Here is a right-angled triangle.
Height: 5.25cm
base: X
the last lenght idk how to say it sorry: 18.75cm
Work out the value of x.

Answer 1

Answer:

${(hypotenuse)}^{2} = {(side)}^{2} + {(side)}^{2} \\ {(18.75)}^{2} = {(5.25)}^{2} + {(x)}^{2} \\ 351.5625 = 27.5625 + {x}^{2} \\ 351.5625 - 27.5625 = {x}^{2} \\ 324 = {x}^{2} \\ x = \sqrt{324} \\ x = 18$

here is your answer
