Describe how you would find the third angle measure in a triangle knowing that one angle measures 63 degrees and the the other m
maxonik [38]

the missing angle is  c=69° .

<u>Step-by-step explanation:</u>

Here we have , a triangle knowing that one angle measures 63 degrees and the the other measures 48. We need to tell e what the missing angle measure must be. Let;s find out :

We know that , by the property of triangle : Sum of all the three angles of a triangle is always 180° . Let angles of triangle be a,b,c  :

⇒ a+b+c=180

In question we have following parameters as :

a=63\\b=48\\c=?

Putting these value in  a+b+c=180 we get :

⇒  a+b+c=180

⇒  63+48+c=180

⇒  111+c=180

⇒  c=180-111

⇒  c=69°

Therefore , the missing angle is  c=69° .

Corresponding sides of similar triangles are proportional. True False
Nutka1998 [239]
True. While the triangle are not congruent, their sides are proportional to each other. This is usually accomplished via a <em>scale factor</em>. For example a triangle with the side lengths 3, 3, and 3, might be similar to a triangle with a scale factor of two, which will have side lengths of 6, 6, and 6.

Suppose that populations of men and women have the following summary statistics for their heights (in
Dominik [7]

Answer:

Step-by-step explanation:

172-162 = 10  

 

We can find the standard deviation of D by adding the variances of the heights and taking the square root:

square root of 81

Representing probability with area

When D= M-W =0, their heights are equal. When the man is taller, D is positive, and when the woman is taller, D is negative. Since we know the distribution of the difference D is normally distributed, the probability that the woman is taller than the man can be found by calculating the shaded area below D=0, in the corresponding normal distribution:

A standard normal curve is plotted on a horizontal axis representing D, that goes from negative 17 to 37. The mean, or mu sub D, = 10. The standard deviations, or sigma sub D = 9. The value 0 is marked. The area under the curve to the left of 0 is shaded, representing the probability that the woman is taller. The area to the right represents the probability that the man is taller.

normalcdf:

lower bound: −9999

upper bound: 0

μ=10

σ=9
