For formality<br>its easy lol

Answer:

Therefore, the length of hypotenuse is: 13 units

Step-by-step explanation:

As the given triangle is a right triangle.

We can find the length of hypotenuse using the Pythagoras' Theorem

Let c be the length of hypotenuse

Using Pythagoras' Theorem for the given triangle

$5^2\:+\:12^2\:=\:c^2$

$\mathrm{Switch\:sides}$

$c^2=5^2+12^2$

$c^2=25+144$

$c^2=169$

$\mathrm{For\:}x^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}$

$c=\sqrt{169},\:c=-\sqrt{169}$

$c=13,\:c=-13$

As the length of hypotenuse cannot be negative. Therefore, the length of hypotenuse is: 13 units

Alex is x years old. June is 7 years older than Alex. In 5 years, their total combined age will be 31 years.

shepuryov [24]

Let Alex's age is x and June's age is y y - x = 7 .........(1)
(x+5) + (y+5) =31
x + y = 21 .........(2)
by adding 1 and 2
2y = 28
y = 14
x = 7
