Answer:64°
Step-by-step explanation:
Using sine rule
Sin(68)/2.8=siny/2.7
Cross multiplying
siny=(2.7xsin68)/2.8 sin68=0.9272
Siny=(2.7x0.9272)/2.8
siny=2.50344/2.8
Siny=0.8941
y=sin(inverse)(0.8941)
y=64 approximately
First we look for the angle of the vector, which will be given by:
tan (x) = (- 2/3)
Clearing x we have:
x = ATAN (-2/3) = - 33.69 degrees.
Which means that the angle is 33.69 degrees measured clockwise from the x axis.
Equivalently the angle is
360-33.69 = 326.31 degrees
326.31 degrees measured counterclockwise from the x axis.
The vector is then:
v = 10 (cos (326.31) i + sin (326.31) j)
answer
v = 10 (cos (326.31) i + sin (326.31) j)
About 204 students would choose summer , I found this because 25% is one quarter of a whole and to get the whole you multiply by four so take 51 and multiply by four to get 204
