The second triangle would be the one that is correct.

Triangles' angle measures correspond to the length of their opposite sides. So 60 degrees corresponds to 14, 90 degrees corresponds to 16.1, and 30 degrees corresponds to 8.

The largest angle in a triangle will have the longest side across from it. This is how we know that the first triangle is not the correct answer, as the largest angle does not have the longest corresponding side.

A circle has a diameter with endpoints at (10,8) and (5,-4) what is the circumference of the circle

mel-nik [20]

Answer:

The circumference of circle is 40.82 units.

Explanation:

The end points of diameter lie on circle. since the coordinates of end points of diameter may be evaluated using

d= $\sqrt{(10-5)^ 2-(8-(-4))^ 2}$

= $\sqrt{25+144}$

= $\sqrt{169}=13$

therefore d = 13 .

The formulae of circumference comprises the length of radius of circle, hence find the radius as half of diameter length r=d/2 = 13/2 = 6.5 ; circumference of circle = $2\pi r$
