The Red Line in the figure is an altitude of triangle hjl. Using right angle trig and properties of equality, y sin L = x = z si

aivan3 [116]

Answer:

$\Large \boxed{\mathrm{\bold{C}}}$

Step-by-step explanation:

$\sf \displaystyle sin(\theta) =\frac{opposite}{hypotenuse }$

$\sf \displaystyle sin(L) =\frac{x}{y}$

$\sf \displaystyle sin(H) =\frac{x}{z}$

$\displaystyle \sf \frac{sinL}{z} =\frac{sinH }{y}$

$\displaystyle \sf \frac{\frac{x}{y} }{z} =\frac{\frac{x}{z} }{y}$

Simplifying the expression.

$\sf \displaystyle \frac{x}{yz } = \frac{x}{yz} \ (true)$

$\displaystyle \sf \frac{z}{sinL} =\frac{y}{sinH}$

$\displaystyle \sf \frac{z}{\frac{x}{y}} =\frac{y}{\frac{x}{z}}$

Multiplying both sides by x.

$\sf yz=yz \ (true)$

A box is filled with 2 blue cards, 4 brown cards, and 6 yellow cards. A card is chosen at random from a box. What is the probabi

Finger [1]

Answer:

Therefore the probability that the card is not brown is $\frac12$ .

Step-by-step explanation:

Probability: Probability is the ratio of the favorable outcome to the total outcome.

$Probability =\frac{\textrm{Favorable outcome}}{\textrm {Total outcome}}$

Given that, a box contains 2 cards blue in color , 4 cards brown in color and 6 cards yellow in color.

Total number of cards= (2+4+6)=12

∴P(getting a brown card)

$=\frac{\textrm{No. of brown card}}{\textrm{Total no. of card}}$

$=\frac{6}{12}$

$=\frac12$

∴P(not getting a brown card)

=1 - P(getting a brown card)

$=1-\frac12$

$=\frac12$

Therefore the probability that the card is not brown is $\frac12$ .
