Ask your teacher at a point 55 feet from the base of a church, the angles of elevation to the bottom of the steeple and the top of the steeple are 40° and 47°, respectively. find the height of the steeple. (round your answer to one decimal place.)

the height of the steeple is 12.8 feet

Step-by-step explanation:

The diagram of the triangle formed is shown in the attached photo.

The triangle formed is triangle ABC and it is a right angle triangle. So angle B is 90 degrees.

Let x represent the height of the steeple.

Let y represent the height from the base of the church to the bottom of the steeple.

Applying trigonometric ratio,

tan # = opposite side / adjacent side

tan 40 = y/55

y = 55tan40

y = 55 × 0.8391 = 46.1505

BC = x + y

tan 47 = BC/55

BC = 55tan47

BC = 55× 1.0724

BC = 58.982

x = BC - y

x = 58.982 - 46.1505

x = 12.8 feet

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
