What basic trigonometric identity would you use to verify that sinx cosx tanx=1-cos^2x

andre [41]

Answer:

$sin^2x+cos^2x=1$ is used to prove the given equation.

Step-by-step explanation:

We have given an equation:

$sinx\cdot cosx\cdot tanx=1-cos^2x$

We will consider right hand side first

tan x can be written as:

$tanx=\frac{sinx}{cosx}$

So, on substituting tan x in the left hand side of the given equation we get:

$sinx\cdot cosx\cdot \frac{sinx}{cosx}$

Cancel common term from denominator and numerator which is cosx we get

$sin^2x$

And we have an identity:

$sin^2x+cos^2x=1$

$\Rightarrow sin^2x=1-cos^2x$

Hence, right hand side is equal to $sin^2x$ .

Assuming both vertical lines are parallel and assuming I'm supposed to find all the unmarked angles...

Angle C:

Supplementary Angles.

x+36=180

180-36=x

x=144

Angle B:

Corresponding Angles.

Angle B ≅ Angle C

144

Angle A:

360 degrees in a quadrilateral

36+144+81+x=360

261+x=360

x = 99
