Does it say anything about slope?
cos0 = √3/2
1 - cos²0 = sin²0
= 1/4 = sin²0
sin in quadrant 4 is negative
sin0 = -1/2
Step-by-step explanation:
2(4*6/2)+2(11*6/2)=24+66=90
6.166666666666667
is the hole answer
Answer:

Step-by-step explanation:
Factorise the numerator and denominator
x² - x - 6 = (x - 3)(x + 2)
x² + 2x - 15 = (x - 3)(x + 5)
Hence
= 
Cancel the factor (x - 3) on the numerator/ denominator leaving
