In ΔPQR, the measure of ∠R=90°, the measure of ∠P=52°, and QR = 9.6 feet. Find the length of RP to the nearest tenth of a foot.

Given:

In ΔPQR, the measure of ∠R=90°, the measure of ∠P=52°, and QR = 9.6 feet.

We need to determine the length of RP.

Length of RP:

The image of the triangle PQR is attached below.

Using the figure, the length of RP can be determined using the trigonometric ratio,

Substituting , and

Thus, we get;

Substituting the values, we get;

Simplifying, we get;

Dividing, we get;

Thus, the length of RP is 7.5 feet.

40%=2/550=1/230=3/1056=14/25

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

1 the 1st term, 3 the 2nd term, 6 the 3rd term,etc.

note the following:

from the 1st term (1) to the 2nd term (3), we go up by 2,from the 2nd term (3) to the 3rd term (6), we go up by 3from the 3rd term (6) to the 4th term (10), we go up by 4, andfrom the 4th term (10) to the 5th term (15), we go up by 5.

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
