(sinA + cosA)/ (secA + cosecA) = sinA* cosA

OlgaM077 [116]

Answer:

<em>Proof below</em>

Step-by-step explanation:

<u>Trigonometric Identities</u>

We'll prove that:

$\displaystyle \frac{\sin A+\cos A}{\sec A+\csc A}=\sin A*\cos A$

Recall:

$\displaystyle \sec A =\frac{1}{\cos A}$

$\displaystyle \csc A =\frac{1}{\sin A}$

Applying those definitions:

$\displaystyle \frac{\sin A+\cos A}{\sec A+\csc A}=\frac{\sin A+\cos A}{\frac{1}{\cos A}+\frac{1}{\sin A}}$

Adding the fractions:

$\displaystyle \frac{\sin A+\cos A}{\sec A+\csc A}=\frac{\sin A+\cos A}{\frac{\sin A+\cos A}{\cos A*\sin A}}$

Dividing the fractions:

$\displaystyle \frac{\sin A+\cos A}{\sec A+\csc A}=(\sin A+\cos A)*\frac{\cos A*\sin A}{\sin A+\cos A}$

Simplifying:

$\displaystyle \frac{\sin A+\cos A}{\sec A+\csc A}=\cos A*\sin A$

Hence proved

What is the value of b?

Tresset [83]

Look at the picture.

d° + c° = 2 · 68° = 136°

b° = 360° - (136° + 104°) = 360° - 240° = 120°

Explanation:
2(4.50) + 2(1.50) = 12
16% of 12 = 1.92
12.00 + 1.92 = 13.92
