Answer:

100 times

Step-by-step explanation:

multiples of 3 on a number cube are 3 and 6

probability of rolling a '3' or '6' is 1/6 + 1/6 = 2/6 or 1/3

1/3 x 300 = 100

The triangle angle sum property states that the measures of the 3 angles of any triangle must add to 360 degrees.
serg [7]

Answer: False

Step-by-step explanation:

Triangle is a polygon with 3 sides. The formula for calculating the sum of angle in a polygon is given as :

(n-2)180

where n is the number of sides , so to calculate the sum of angles in a triangle we have :

(3-2) 180

= 1 x 180

= 180

Therefore : The triangle angle sum property states that the measures of the 3 angles of any triangle must add to 180 degrees.

What is the value of x, rounded to the nearest degree? x ≈ ° According to the manufacturer, if the angle the ladder forms with t
DerKrebs [107]

The measure of the value of x is 70.52 degrees.

Given

A 12-foot ladder is placed 4 feet away from a house as shown.

According to the manufacturer, if the angle the ladder forms with the ground, x, is between 70° and 75°, then it meets safety standards.

<h3>What is cos angle?</h3>

The cos theta is defined as the ratio of the side adjacent to the angle and the hypotenuse.

The following formula is used to calculate the value of x;

\rm Cosx=\dfrac{Side \ adjacent \ to \ angle}{Hypotenuse}\\

Where the side adjacent to angle = 4 and hypotenuse is 12.

Substitute all the values in the formula;

\rm Cosx=\dfrac{Side \ adjacent \ to \ angle}{Hypotenuse}\\\\\rm Cosx=\dfrac{4}{12}\\\\\rm Cosx=\dfrac{1}{3}\\\\x=Cos{-1}(\dfrac{1}{3}\\\\x= 70.52 \ degrees\\\\

Hence, the measure of the value of x is 70.52 degrees.

write a problem that can be modeled by the equation 2x+40=60 then sovle the equation and explain the solution in the context of
sergiy2304 [10]
2x + 40 = 60 (Subtract 40 from both sides)
     - 40   - 40
--------------------------------
2x = 20 (Divide both sides)
2x/2 = 20/2
x = 10 (This is your final answer)

Suppose sin u= x and u is between 0 and pi/2. what is sec u? ...?
denpristay [2]
The question should be accompanied with choices, below are the choices:

a) sqrt(1-x^2) 
<span>b) x/sqrt(1-x^2) </span>
<span>c) sqrt(1-x^2)/x </span>
<span>D) 1/sqrt(1-x^2)
</span>
The answer should be <span>c) sqrt(1-x^2)/x . 

</span><span>cos u = sqrt (1 - sin^2 u) = sqrt(1 - x^2), and cot u = cos u / sin u.</span>
