You must show how you get your answer.
(3)
The sunglasses cost €70
The exchange rate is €1 = £0.895
Emad says, "The sunglasses cost less than £60"

i'm not entirely sure

step-by-step explanation:

if you ask home depot or lowe's they might be able to you out

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

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
