Answer:

B) 6

Step-by-step explanation:

It is 45, 45, 90 degrees right triangle, the ratio of the triangle 1:1:√2

Hypotenuse = 3√2*√2

= 3*2

= 6

Thank you.

Answer:

6


Step-by-step explanation:

Hypotenuse is the side that is opposite of the 90 degree angle (the longest side as well).

As seen in the triangle, the side opposite of 45° angle is known AND we want to find the hypotenuse.


Which trigonometric ratio relates opposite with hypotenuse?

SINE

We can write:

[tex]sin(A)=\frac{opposite}{hypotenuse}\\sin(45)=\frac{3\sqrt{2}}{h}[/tex]

We let hypotenuse be [tex]h[/tex]. Also we know that [tex]sin(45)=\frac{1}{\sqrt{2}}[/tex]

Now we can solve for [tex]h[/tex]:

[tex]sin(45)=\frac{3\sqrt{2}}{h}\\h*sin(45)=3\sqrt{2}\\h=\frac{3\sqrt{2}}{sin(45)}\\h=\frac{3\sqrt{2}}{\frac{1}{\sqrt{2}}}\\h=3\sqrt{2}*\frac{\sqrt{2}}{1}\\h=6[/tex]

(we used the identity [tex](\sqrt{a})(\sqrt{a})=a[/tex])

2nd answer choice is right. Hypotenuse is 6.
