-4,-3,-2 if you add them up you should get -9
2, 3, 13
Explanation: You take a^2+b^2=c^2 and substitute the side lengths and solve until you find one where a^2+b^2 actually equals c^2 and that’s your answer
I think that you have forgot to divide at the end, like the first one would be 28 because you would divide by an estimate of 2
Triangles ABD and BCD are similar, because they are both right and share a common angle, and thus all three angles are equal.
This means that we can set the proportion
Plug the numbers and we have
Solve for 
:
The values of x and y from the given diagram are 47 ad 86 degrees respectively
<h3>Circle theorem</h3>
From the given circle, the triangle HJL is a right triangle.
Determine the value of y
43 = 1/2 <y
<y = 43 * 2
<y = 86 degrees
Since the sum of angle on a straight line is 180 degrees, such that;
x+90+43 = 180
x + 133 = 180
x = 47 degrees
Hence the values of x and y from the given diagram are 47 ad 86 degrees respectively
