You need to set this up with a proportion and solve. 18/x-5 = 13.5/12.
cross multiply 13.5x-67.5=216
now solve for x
13.5x=283.5
x=21
the missing side is equal to 21-5, which is equal to16

H + 169 = 759 solve for h

steposvetlana [31]

Answer:

h = 590

Step-by-step explanation:

To find x, rearrange the equation to where h is on its own side.

Rearranged equation:

$759 - 169 = h$

Since 169 added to h was to find 769, 169 subtracted from 759 represents h.

Solve:

$759 - 169 = 590$

590 = h.

Help me please please

Wittaler [7]

Answer:

It is right

Step-by-step explanation:

Because the hypotenuse must be greater than all the legs, we have that $17$ is the hypotenuse. So, we want to determine if $8^2+15^2=17^2$ .

$8^2=8*8=64\\15^2=15*15=225\\17^2=17*17=289\\225+64=289\\$

This means the triangle is indeed right!
