There is a stack of 8 cards, each given a different number from 1 to 8. Suppose we select a card randomly from the stack, replac

Serhud [2]

Four of the cards have an even number, so the probability of drawing an even is $\dfrac48=\dfrac12$ .

Only two cards have a number greater than 6 (7 and 8), so the probability of drawing one of them is $\dfrac28=\dfrac14$ .

The probability of both events happening is

$\dfrac12\times\dfrac14=\dfrac18$

Find the measure of the missing angles in the triangle below round your answer to the nearest degree

navik [9.2K]

Answer:

a. 40°

b. 21°

Step-by-step explanation:

a. Reference angle = θ

Opposite = 5

Adjacent = 6

Apply TOA:

$Tan (\theta) = \frac{Opp}{Adj}$

$Tan (\theta) = \frac{5}{6}$

$\theta = Tan^{-1}(\frac{5}{6})$

$\theta = 40$ (nearest degree)

b. Reference angle = x

Opposite = 5

Hypotenuse = 14

Apply SOH:

$Sin (x) = \frac{Opp}{Hyp}$

$Sin (x) = \frac{5}{14}$

$x = Sin^{-1}(\frac{5}{14})$

$x = 21$ (nearest degree)
