Write a real world problem with a percent that can be solved by using the proportion 3/b=60/100

A tree of 60 feet casts the shadow of 100 feet, at the same time, what is the length of the shadow of a boy who is 3 feet tall ?

Solution :

Let b represents the length ( in ft ) of the shadow of the boy,

∵ Height of the boy = 3 ft,

So, the ratio of the height of boy and his shadow =

Now, the tree of 60 ft long casts 100 ft shadow,

So, the ratio of height of tree and its shadow =

At the same time,

Which is the required equation.

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.

the correct option is b
