Answer:

∠ C = 55°

Step-by-step explanation:

∠ W and ∠ A are adjacent angles and are supplementary, then

∠ A = 180° - ∠ W = 180° - 134° = 46°

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the 2 angles from 180 for ∠ C

∠ C = 180° - (46 + 79)° = 180° - 125° = 55°

Fill in the blank so that 81x2+_ x+81 is a perfect square trinomial. 81x²+_____ x+81

densk [106]

the blank is 162

since 81 and 81 are both perfect squares the middle term (blank) will be the product of their roots times 2

√81=9

√81 =9

Which function families have vertical symmetry?

Nady [450]

The functions which are even are symmetric to y-axis. By even functions, it means that f(x) = f(x) for all the domain values. Thus even functions for example, x^2, 1+x^2, cosx, x^4 all follow the conditions i.e. f(x) = f(x) and thus they are symmterical to y-axis.

Charlene records the number of pieces of red colored candies in ten bags of candy of assorted colors. find and interpret the mea

BaLLatris [955]

To calculate the mean absolute deviation, you first must find the mean of the data and then find the difference between each piece of data and the mean.

Please see the attached picture for the work.

The mean absolute deviation is approximately 1.48.

This means that the numbers of candies in the 10 bags are all very close to one another. There is not much variation.

In triangle XYZ, shown above, what is the value of cos(X)?

adell [148]

Answer:

Step-by-step explanation:

Sine we can figure out side XY by using Pythagorean Theorem (A^2+B^2=C^2) and find that XY= 5, We can use Soh Cah Toa (The ways I remember to use value charts) and we know that Cosine uses Adjacent over Hypotenuse in which therefore the answer would be 5/13
