X is a positive acute angle. That means x is located in the first quadrant and has positive value in sin, cos, tan.
The formula of trigonometry ratio
cos x =

sin x =

From the formula of cosine
cos x =


from the formula above, adjacent side is 3 units, and hypotenuse is 5 units
Draw a right triangle to illustrate the location of the sides. See image attached.
To find the ratio of sine, we need to find the length of opposite side using pythagorean theorem
3² + (opposite)² = 5²
9 + (opposite)² = 25
(opposite)² = 25 - 9
(opposite)² = 16
opposite = 4
The length of opposite side is 4 units
Find sin x
sin x =

sin x =
Answer:
95.04 pounds
122.54 US dollars
Step-by-step explanation:
I had to do the math in US dollars first then turn it into pounds.
All you do is this
136.16 * -.10 (US dollars)
13.616(US) 10.56(pounds)
Subtract 13.616 from 136.16 to get
122.544 or 122.54 (US)
95.04(pounds)
