60.8

Using Pythagoras' theorem it is 12 mm

No because they don't comply with Pythagoras' theorem.

Yes.

9,3,6 The dimensions given above would not be suitable for a right angled triangle which presumably the question is asking about. The dimensions suitable for a right angled triangle in the question are: 9, 12, 15.

Yes they do. We find this by applying the pythagorean theorum. Since 9^2 + 12^2 = 15^2, they form a right triangle.

It is a right angle triangle so area = 0.5*15*8 = 60 square feet

The least common multiple of 912 and 15 is 4560.

Add the squares of the two smaller sides. Is it equal to the square of the biggest side? If yes, it is a right angled triangle. 82 + 152 = 64 + 225 = 289 172 = 289 The same, so it is right angled.

Assuming this is a right triangle. the tan of an angle is the side opposite over the side adjacent. We know the side opposite, we need to find the side adjacent, we will assign this unknown side temporarily as x. tan(15) = 1.2 / x x = 1.2 / tan(15) x (the side adjacent) is approx. 4.49 m

Yes.

False. It can't be.In a right triangle, the sum of the squares of the two short sides is equal to the squareof the longest side.122 = 144152 = 225-------------sum = 369202 = 400, not 369.So these are not the sides of a right triangle.

The least common multiple of the numbers 912 and 15 is 4,560.
