what is the greatest angle measure in the diagram? 95o
105o
119o
180o

The 4 angles add up to 360 degrees
so 
50x + 10 = 360
50x = 350
x = 7

so largest angle = 15x + 14  = 15(7) + 14 =  119 degrees

119

thats your answer

The Critical points and the Trig Functions are not really that different than the methods you always use for finding those critical points for any other types of functions and the Critical points are points that the derivative is set as a 0 or it can be undefined.
