Answer:

X = 0.2

Step-by-step explanation:

5x + 10 = 11

-10 -10 remove 10 from each side to get x by itself

5x = 1

Divide both sides by 5

x = 0.2

Find tan2θ if θ terminates in Quadrant IV and cosθ =3/5 .

Liula [17]

Answer:

The answer to your question is $\frac{-8}{3}$

Step-by-step explanation:

Data

cos Ф = 3/5

tan2Ф = ?

Quadrant IV

Process

1.- Remember that tanФ = $\frac{Opposite side}{Adjacent side}$ and cos Ф = $\frac{adjacent side}{hypotenuse}$

then, adjacent side = 3 and hypotenuse = 5

2.- Calculate opposite side

O² = h² - a²

O² = 5² - 3²

O² = 25 - 9

O² = 16

O = 4

3.- Calculate the tan 2Ф

tan 2Ф = 2( $\frac{-4}{3}$ ) The opposite side is negative in the fourth

quadrangle

tan 2Ф = $\frac{-8}{3}$
