Cos2a=1-2sin^2a for all values of a.

pickupchik [31]

$cos2a= cos^{2} a- sin^{2} a \\ but \ cos^{2} a + sin^{2} a=1 \\ i.e. \ cos^{2} a=1- sin^{2} a$
Therefore,
$cos2a=1- sin^{2} a- sin^{2} a \\ =1-2 sin^{2} a$

Solve the equation. Show all of your work. 1/59X + 60) = 2/3x- 2

vivado [14]

Step-by-step explanation:

1/5x+60=2/3x-2

subtract 1/5x from 2/3x

when you do that you should get 0.46x repeating

then you add two to 60

you should get 62

62=0.46x

divide x

you get 134.7
