Which side of triangle QRS is the longest?

Explanation:

Refer to the diagram below. The longest side of a triangle is always opposite the largest angle. Angle Q = 80 is the largest angle, so the opposite side RS is the longest side.

Side note: the smallest side is always opposite the smallest angle

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
