I) express cos 30 in terms of cos 0.
32. il cos a = 2 (1 in quadranı iv) and sinb = (b in quadrant ii )find,

(i) sin(a - b)
(iii) cos(a+b)
23. find the exact value of by using the sum or difference formulas;

i) sin 105 degrees
(ii) cos 225°

i need more info. are you looked to see there mph? how much they deliver? how far they go?

step-by-step explanation:

answer:   rotate 270° clockwise about (7, 1) and reflect across the line x = 7

step-by-step explanation:

because i took test

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
