Answer:
? = 57
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos ? = adj/ hyp
cos ? = 14/26
Taking the inverse cos of each side
cos ^-1 ( cos ?) = cos ^-1 ( 14/26)
? = 57.42102961
To the nearest degree
? = 57
CQE is a right angle. Hope this helps!!!
Point-slope form is y-y1=m(x-x1)
m=1
y1=11
x1=-2
y-11=1(x-(-2)
