An obtuse triangle has measurements of 100°,60° and 20°. if the longest side of this triangle is 20ft what is the length of the shortest side?

The longest side of a triangle is always opposite the largest angle of a triangle.

If the smallest angle of the triangle is 20 degrees, then the shortest side is opposite to it. Using this information, we can form the equality

20/100(longest leg/biggest angle) = x/20(shortest leg/smallest angle)

We can cross multiply this to get 400 = 100x. From here it is a simple "find x" and the shortest side is 4 feet.

see below

step-by-step explanation:

x+2> 6

subtract 2 from each side

x+2-2 > 6-2

x > 4

there is an open circle at 4 since is it is greater than and the line goes to the right
