Mathematics
1 answer:
laiz [17]3 years ago
4 0

Step-by-step explanation:

  • cos θ = 2/3

\quad \twoheadrightarrow\sf {cos \; \theta = \dfrac{Base}{Hypotenuse} } \\

Hence, base = 2 units and hypotenuse = 3 units.

\quad \twoheadrightarrow\sf { H^2 = B^2 + P^2} \\

\quad \twoheadrightarrow\sf { P^2 = H^2 - B^2} \\

\quad \twoheadrightarrow\sf { P^2 = (3)^2 - (2)^2} \\

\quad \twoheadrightarrow\sf { P^2 = 9- 4} \\

\quad \twoheadrightarrow\bf { P = \sqrt{5}} \\

Now, we know that :

\quad \twoheadrightarrow\sf {cosec \; \theta = \dfrac{Hypotenuse}{Perpendicular} } \\

\quad \twoheadrightarrow\bf{cosec \; \theta = \dfrac{3}{\sqrt{5}} } \\

Therefore, the required answer is 3/√5.

Guys answer ASAP PLZ how many 1/2 can go into 10 3/4?????
Leona [35]

Answer:

21

Step-by-step explanation:

There are 2 halfs in 1 number.

Lets start with your whole number: 10

You double 10 because there are two halfs in each whole number making it equal 20.

Now you have 3/4

There would be 1 half in this number because it's a fraction and not a whole number.

You would be left over with 1/4

Your answer is 21

Hope this helps! Goodluck
