Assuming the picture isn’t to scale
X=61 because the two angles create a straight angle or 180° so you subtract 119 from that to find the measurement of the angle x
y=79 because the triangle in total is 180° and we know x=61 so now we do the equation and get 64. so we know 64 is that portion of the triangle so we then add the other angle we know the measurement of which is 37° to get 101 then with that you will subtract it from 180 (the total measurement of the triangle) and get 79°
hope this helps

Answer:

For x it is 54.5 or 305.5 and for y it is 58.4 or 301.6. Hope this helps.

I would get the protractor extension from the chrome web store it is free and easy to use.

From his eye, which stands 1.61 meters above the ground, Jacob measures the angle

bixtya [17]

Step-by-step explanation:

we have a right-angled triangle, that is "hovering" 1.61 m above the ground.

the Hypotenuse (the side opposite of the 90 degree angle) is the line of sight from the eye to the top of the skyscraper.

one leg is the height of the skyscraper (minus the 1.61 m).

the other leg is the ground distance from Jacob to the skyscraper (281 m).

we know already 2 angles : the 90° angle between the ground distance and the skyscraper height. and the 25° between the ground distance and the line of sight.

and as we know that the sum of all angles in a triangle is always 180°, we know that the third angle (between the line of sight and the skyscraper height) is

180 - 90 - 25 = 65°

now we can use the law of sines

a/sin(A) = b/sin(B) = c/sin(C)

(the ratio between a side and its opposing angle)

to get all missing side lengths.

the 25° angle is opposite of the skyscraper height, and the 65° angle is opposite of the ground distance (the only side length we know so far).

so,

height/sin(25) = 281/sin(65)

height = 281 × sin(25)/sin(65) = 131.0324519... m

to get the full height of the skyscraper, we need to add the 1.61 m that the described triangle was "hovering" above ground.

therefore, the height of the skyscraper is

131.0324519... + 1.61 = 132.6424519... ≈ 132.6 m

You are to give an injection of a drug. The dosage is 0.4 mg per kilogram of bod The concentration of the drug in vial is listed

shusha [124]

Answer:

We inject 60.9628 milliliters of dosage.

Step-by-step explanation:

Given : You are to give an injection of a drug. The dosage is 0.4 mg per kilogram of bod The concentration of the drug in vial is listed as 500 ug/ml. The patient's chart Hosts weight as 168 pounds.

To find : How many milliliters (= cc) are you to inject?

Solution :

We know that,

1 pound = 0.453592 kg,

Patient's weight = 168 pounds

Patient's weight in kg = $168\times 0.453592=76.203456$ kg

The dosage is 0.4 mg per kilogram of bod.

So, dosage of patient weight = $0.4 \times 76.2035\ mg = 30.4814\ mg$

We know, 1 micro gram = 0.001 mg

Concentration of drug is given by,

$500\ \text{micro grams/ml}= 500\times 0.001\ \text{mg/ml} = 0.5\ \text{mg/ml}$

Now we are supposed to find milliliters inject,

So, milliliters of dosage required to inject is

$d= \frac{30.4814}{0.5} = 60.9628$

Therefore, We inject 60.9628 milliliters of dosage.

What is the probability that a random sample of 12 second grade students results in a mean reading rate of more than 95 words pe

mihalych1998 [28]

The probability that a random sample of 12 second grade students results in a mean reading rate of more than 95 words per minute is 0.4582.

Given that the population mean, $\mu$ = 90 wpm

The standard deviation of the population , $\sigma$ = 10

Sample size, n = 12

Sample mean, $\bar x$ = 95

The reading rate of students follows the normal distribution.

Let z = $\frac{\bar x - \mu}{\frac{\sigma}{\sqrt n} }$

= $\frac{95 - 90}{\frac{10}{\sqrt 12} }$

= 1.732

Probability that the mean reading exceeds 95 wpm = P( $\bar x$ >95)

= P(z>1.732)

= 1- P(z<1.732)

= 0.4582

[The value 0.4582 found from the area under the normal curve using tables].
