Question

Can someone help me on this?

Answer 1

12√2

Explanation:

45-45-90 special right triangles follow the form of x,x,x√2

Where both the sides that are across from the same angle (45) are equal in length and the hypotenuse is that value multiplied by the √2

Answer 2

x =
`12√(2)` the third answer

Explanation:

∵ The triangle is right angled Δ

∵ The triangle has two equal legs of the right angle each = 12

∴ The length of the hypotenuse =
`\sqrt{(12)^(2)+12^(2)}=√(144+144)=√(288)=12√(2)`
