Answer:
10 feet higher.
Pine tree measure = 40 feet in height
Step-by-step explanation:
This is because the Flag pole of 50 feet in measure cast a shadow of 15feet and nearby to the pine tree (meaning same dilation would occur for such shadow) where pine tree shadow is given measure of 12 feet.
Flag Pole multiplier = 50 / 15 = 3 1/3
Pine Tree true measure = 12 x 3 1/3 = 40 feet in height
Answer: 11
Step-by-step explanation:
Since the equation of circumference is 2(r)pi
if 22pi=2(r)pi
then 22=2r
22=2r
r=11
Answer:
Step-by-step explanation:
tanx + cotx = secx / sinx
take left hand side
=tanx + cotx
=sinx/cosx + cosx/sinx
=sinx*sinx+cosx*cosx/sinx*cosx
=sin^2x + cos^2x/sinx*cosx
=1/sinx*cosx
=1/cosx * 1/sinx
=secx/sinx
at second last step i changed multiplication sign into divide sign and write the reciprocal of 1/sinx which is sinx.
Answer:
