Alona [7]

Answer:

260 cm

Step-by-step explanation:

Each 1/00 of a meter is 1 cm, so 65/100 meters is 65 cm. If that is the length of paper required for 1 kite, then 4 times that length will be required for 4 kites.

The paper required for 4 kites is ...

If cos theta=-2/3, which of the following are possible (Help asap)

alexgriva [62]

Answer:

The correct option is B) $sin\theta=\frac{\sqrt{5}}{3}$ and $tan\theta=\frac{\sqrt{5}}{2}$

Step-by-step explanation:

given $cos\theta=-\frac{2}{3}$

Since, $cos\theta=\frac{base}{hypoteneous}$

it means prependicular of right angled triangle can be calculated by pythagoras theorem as:

base² + prependicular² = hypoteneous²

2² + prependicular² = 3²

4 + prependicular² = 9

prependicular² = 9 - 4

prependicular² = 5

prependicular = √5

Since, $sin\theta=\frac{prependicular}{hypoteneous}$

$sin\theta=\frac{\sqrt{5}}{3}$

Since, $tan\theta=\frac{prependicular}{base}$

$tan\theta=\frac{\sqrt{5}}{2}$

Hence, the correct option is B) $sin\theta=\frac{\sqrt{5}}{3}$ and $tan\theta=\frac{\sqrt{5}}{2}$
