Use distributive property
-28y+8y= -20y
The answer is 106.5 by using sin(28) = 50/x
First, you distribute the 3 into the brackets,
<span>3(x - 2) + 5x
=</span><span>3(x) + 3(-2) + 5x
=3x - 6 + 5x
Adding the like terms, 3x and 5x, gives you
=8x - 6</span>
use the Pythagoras theorem method
a squared plus b squared equals c square
Flipping over the trigonometric functions of sine, cosine and tangent we have the following respectively
1/cscФ (sinФ), 1/secФ (cosФ) and 1/cotФ (tanФ). These are the identities for which they numerically equal when the numerator and denominator of these fractions are swapped.
