The sears tower in chicago is 1454 feet high. sketch and find the angle of elevation from a point 750 feet from the base to the top of the tower. relate your answer to the nearest tenth.

The correct answer is 62.7

Step-by-step explanation:

Use tan (tan= opp/adj)

Input your values:

Height- 1454

Length from Base- 750

Equation:

tan(x)=1454/750 (Gives you 1.938...)

The use the inverse of tan and use 1.938

Equation:

atan(1.938)= 62.07

Hope this helped you out :}

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
