4.) The Ferris wheel at the landmark Navy Pier in Chicago takes 7 minutes to make one full rotation. The
height H in feet above the ground of one of the six-person gondolas can be modeled by:
H(t) = 70sin 2pi/7 (t - 1.75) + 80, where t is time in minutes. If you are loaded onto the gondola at 11 AM
how far off the ground will you be at 11:03?

x=30

step-by-step explanation:

cant open file sorry!

step-by-step explanation:

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.
