Step-by-step explanation: We are given to find the value of x from the following trigonometric equation:

sin55=cosx

We know that the sine of any acute angle is equal to the cosine of its complement and cosine of any acute angle is equal to the sine of its complement.So, from equation (i), we get

sin55 ∘ =cosx

⇒sin55 ∘ =sin(90 ∘−x)

⇒55 ∘ =90 ∘ −x

⇒x=90 ∘ −55 ∘

⇒x=35 ∘

Thus, the required value of x is 35°.

Of all customers purchasing automatic garage-door openers, 70% purchase a chain-driven model. Let X = the number among the next
otez555 [7]

Answer:

P(X > 10), n = 15, p = 0.7

P(X > 10) =P(10 < X ≤ 15) = P(11 ≤ X ≤ 15) = P(X = 11, 12, 13, 14, 15)

=P(X = 11) + P(X =12) + P(X = 13) + P(X =14) + P(X = 15) (because these are disjoint events)

What the heck do i do with this
Ad libitum [116K]
Use the law of cosines to find a: a^2=b^2+c^2-2bc (cos(A))

So to use the given numbers you get: a^2=27^2+45^2-2(27)(45)(cos(53))

Which would come out to equal about 35.94

so a=35.9
