Answer:

x = √(w(w+z))

Step-by-step explanation:

The idea with a right-triangle figure of this sort is that all of the triangles are similar. Here, x is the short side of ∆ABC, and the hypotenuse of ∆BDC. This suggests you want to write a similarity statement involving the short side and hypotenuse.

BC/AC = DC/BC . . . . . short side/hypotenuse

BC² = AC·DC . . . . . . cross multiply

x² = (w+z)w . . . . . . substitute letter values

Taking the square root and rearranging to the form of the applicable answer choice, this is ...

$\boxed{x=\sqrt{w(w+z)}}$

I need help finding CR, AB, and CAB

aleksandrvk [35]

Answer:CR= 53

AB = 118

CAB = 236

Step-by-step explanation: a whole is circle is equal to 360 degrees and when you see the two parts which dint have an angle, they look the same size. So I pluses 53 and 71 than subtracted from 360. Which then I divided it by two then you get the angle for A to B.

Hope this helped and hope this is the correct answer.

Given f(x)=x^3+2x+k.<br> and x+1 is a factor of f(x), then what is the value of k?

Ludmilka [50]

Answer:

k = 3.

Step-by-step explanation:

By the Factor Theorem. if x+a is a factor of f(x) then f(-a) = 0.

Here we use f(-1):

f(-1) = (-1)^3 + 2(-1) + k = 0

-1 - 2 + k = 0

k = 3.

Two apples and three peaches cost $1.65. three apples and two peaches cost $1.60. what is the cost of one peach

marta [7]

Apples = $.30
Peaches = $.60

You can get this by setting up a system of equations that looks like this.

2x + 3y = 1.65
3x + 2y = 1.60

Where x is the amount of apples and y is the number of peaches. Then you can solve using any of the methods (I would suggest elimination for ease).

Find the measure of angle y. Round your answer to the nearest hundredth. (please type the numerical answer only) A right triangl

andriy [413]

For this case we have the following trigonometric relationship:
cos (y) = 8/13
Clearing the value of and we have:
y = Acos (8/13)
Calculating the angle we have:
y = 52.02012756 degrees
Rounding off we have:
y = 52.02 degrees
Answer:
the measure of angle and is:
y = 52.02 degrees
