Determine which length form a right triangle
To do this, we make use of Pythagoras theorem where the square of the largest length = the sum of the squares of the other lengths
So:
(1) 12, 35, 37 --- Yes



(2) 16, 30, 34 --- Yes



(3) 18, 24, 42 --- No




(4) 20, 21, 29 -- Yes



Answer:
this is not the answer but it might help you find the answer
Step-by-step explanation:
The area of a regular decagon can be calculated using the formula for finding the area of a general regular polygon. Area of a Regular Polygon = 12 x Perimeter x Apothem. The diagram of a regular decagon ABCDEFGHIJ is given above.
