If x is a positive acute angle and cos x = 3/5, find the value of sinx.
Dima020 [189]
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 = \dfrac{\text{adjacent}}{\text{hypotenuse}}
sin x = \dfrac{\text{opposite}}{\text{hypotenuse}}

From the formula of cosine
cos x = \dfrac{3}{5}
\dfrac{\text{adjacent}}{\text{hypotenuse}}= \dfrac{3}{5}
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 = \dfrac{\text{opposite}}{\text{hypotenuse}}
sin x = \dfrac{4}{5}

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)

It might be a bit confusing, but the answers are up top.
