Answer: x = 12
Step-by-step explanation:
We can see two triangles rectangles, we will use the angle S to solve this, as this angle is common to both triangles.
We know that:
cos(S) = adj cathetus/hipotenuse.
Then we have, for the triangle SRT.
Cos(S) = 9/SR.
for the big triangle, SQR, we have:
Cos(S) = SR/(9 + 16)
now we can find the quotient of those two equations and get:
cos(S)/cos(S) = 9/Sr*(9+16)/SR
SR^2 = 9*(25)
SR = 15.
Now with this side we can find the value of x.
We can use the Pythagorean theorem in the triangle SRT, where the sum of the squared cathetus is equal to the hypotenuse:
9^2 + x^2 = 15^2
x = √(15^2 - 9^2) = 12

Step-by-step explanation:
because the letters match up for the sides of each triangle
The answe is c and also u only divided the denominator not the whole fraction I’m waffling
The problem is modelled as right angle triangle, shown in the diagram below

Using the trigonometry ratio of sine
Answer:
(100 - 8<em>n</em>) is our equation, with 100 being the gift card balance, 8 being the cost of each album, and n being the number of albums.
When n = 6, the equation equals 52. This means that you have $52 left after purchasing 6 albums.
