Question

Help me please with math

Answer 1

Step-by-step explanation:

We know that the pythogoras rule says that

${h}^{2} = {p}^{2} + {b}^{2}$

In the first diagram,

The Hypotenuse is already provided so we can find the answer easily :)

Let's solve!!

1) Let the unknown length(i.e. the base ) be x² yd.

According to the question

${h}^{2} = {p }^{2} + {b}^{2}$

${15}^{2} = {12}^{2} + {x}^{2}$

$225 = 144 + {x}^{2}$

$= {x}^{2} = 225 - 144$

$= > {x}^{2} = 81$

$= > x = \sqrt{81} = 9$

Hence the base of the first figure is 9 yd.

Let's solve this as well!!

2) Let the hypotenuse be x.

${h}^{2} = {b}^{2} + {h}^{2}$

${x}^{2} = {2}^{2} + {5}^{2}$

$= {x}^{2} = 4 + 25$

$= {x}^{2} = 29$

$= x = \sqrt{29}$

$x = 5.3851648071345$

So therefore the unknown side is 5.3851648071345 in

Hope it helps you!!
