For a the answer is: 48 km/hr. For b the answer is: The distance could be longer, so if she took hours she would have to drive faster; or if starter distance she would have driven slower
Cosine is the ratio of the adjacent side to the hypotenuse.
In short, we have this equation
cos(angle) = adjacent/hypotenuse
In the case of cos(A) = 18/19.5 we can see that
adjacent = 18
hypotenuse = 19.5
The side of 18 cm is next to angle 2, so the 18 cm side is adjacent to angle 2 (in contrast, the 7.5 cm side is the opposite leg in relation to angle 2)
So that's why the answer is angle 2
In other words, replace the '2' angle marker with 'A' to be able to write cos(A) = 18/19.5
(0,-1)(1,0)(2,3)(3,8)(4,15)

Answer:
Step-by-step explanation:
x=81
63+36+x=180
99+x=180
99+81=180
y and z both equal 81
13+y+z=180
180-13=167
167/2 is 83.5
13+83.5+83.5
13+167
180
