The red thing at the top is a right angle. Find the missing side lengths and leave answers as radicals in simplest form ILL GIVE

atroni [7]

Answer:

A. x = 13

y = (13√3)/3

Step-by-step explanation:

Reference angle = 30°

Hypotenuse = (26√3)/3

Adjacent = x

Opposite = y

✔️Apply CAH to find x:

Cos 30 = Adj/Hyp

Cos 30 = x/(26√3)/3

√3/2 = x*3/(26√3) (cos 30 = √3/2)

√3/2 = 3x/(26√3)

Cross multiply

2*3x = (26√3)*(√3)

6x = 26*3

6x = 78

x = 78/6

x = 13

✔️Apply SOH to find y:

Sin 30 = Opp/Hyp

Sin 30 = y/(26√3)/3

Sin 30 = y*3/(26√3)

½ = 3y/(26√3) (sin 30 = ½)

Cross multiply

2*3y = (26√3)*1

6y = 26√3

Divide both sides by 6

y = (26√3)/6

y = (13√3)/3

Francisco rides a carousel with a diameter of 30 m. During the ride, the carousel rotates a total of 7000 degrees. What is the d

Ainat [17]

360 degrees = 1 full rotation
7000/360 = 19.4444... turns

perimeter or circle = 2 $\pi$ r
diameter = 30m
radius =15m

2 $\pi$ (15) = 94.24777961 per turn

94.24777961 x 19.444... turns = 1832.595714 meters traveled

Rounded = 1832.60 meters

36 out of 100 randomly selected taxpayers knew about tax incentives for installing energy-saving furnaces. Find a 90% confidence

tresset_1 [31]

Answer:

The 90% confidence interval for the population proportion who knew about the incentives is (0.28, 0.44).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of $\pi$ , and a confidence level of $1-\alpha$ , we have the following confidence interval of proportions.
