Answer 2

Answer:

If it is a right angle triangle then one of the angles is 90 degrees. If another angle is 45 degrees then the third angle must also be 45 degrees.

Now if the two base angles are the same then the triangle is isosceles so the two legs are the same. The height of a right angle triangle is one of the legs so the other leg must be 27cm.

To get the hypotenuse we just use Pythagoras’ theorem or we could use our trigonometric ratios, either way we’re going to get 272–√ for the hypotenuse.

If we use Pythagoras’ theorem then Hypotenuse = 272+272−−−−−−−−√=2∗272−−−−−−√=272–√.

If we use our trigonometric ratios sin(45°)=cos(45°)=1/2–√

Hypotenuse = 27/(1/2–√)=272–√
