If sin α=(12/13), and cos α=(5/13), then tan α = ?

Sin α  =  12/13             opposite/hypothenue
cos α  =  5/13              adjacent/hypothenue
tan α  =  12/5                opposite/adjacent

The writing is like bold so i can’t see it well

First locate the turning point (vertex) of the graph. which is at the coordinates x=5 and y=9 or (5; 9).to determine whether it's a maximum or mininum value, you have to discern whether the vertex's y-value is the highest value or lowest value the graph can reach. since the vertex's y-value, 9 is the highest value the graph can reach, it will be a maximum.another basic way to determine whether the vertex's value is max or min is to see if the graph is smiling or sad. if it's smiling, the turning point/vertex would be a minimum, while a sad parabola would have a maximum y-value at the vertex.
