What basic trigonometric identity would you use to verify that sin x cos x tan x =1-cos^(2)x?

Step-by-step explanation:

1. Keeping on mind that , you have:

2. Simplify it, then you obtain:

3. Keeping on mind that , you obtain:

Step-by-step explanation:

We want to verify that;

We take only the expression on the left hand side and work to get the expression on the right hand side.

We cancel the common factors to get;

We now use the Pythagorean identity;

We make the subject to obtain;

as required.

The basic trigonometric identity we used is

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.
