Find WV<br> A 7<br> B 23<br> C 84<br> D 145
user100 [1]
Comparing the two triangle above, we can state:

a) The side WZ = side YZ
b) The side VZ = XZ
c) Angle WZV = Angle XZY (Vertical Angles)
d) XY is parallel to WV
e) So, Angle XYZ = Angle VWZ

Thus, we can conclude that the two triangles are exactly equal in measure. All the sides and angles of the triangle have the same measure.

So, Side WV = Side XY

12x - 61 = 3x + 2
12x - 3x = 2 + 61
9x = 63
x = 7

So, length of WV will be = 12(7) - 61 = 23

Thus, the answer to this question is 23

Solve the triangle for x.
nalin [4]

Answer:

90.4°

Step-by-step explanation:

Use Law of Cosines to solve:

12² = 9² + 8² - 2(9)(8)Cos X

  144 = 81 + 64 - 144Cos X

     -1 = -144Cos X

         -1/144 = Cos X

            Cos^-1 (-1/144) = X

                     X = 90.39789056°

Marie's journal is 400 pages long. She has used 20% of the journal. How many pages has she used so far?
vitfil [10]

Answer:

40/ or /80

Step-by-step explanation:

Because 400 is a lot and if it's 100% is 400 right so we do 80% what would that be? we don't know right.

What about 100 pages that would be (im pretty sure) 40% or 50%.

I hope this helped!!!

GOODLUCK!!!!!!!!!!

Solve for possible values of x. 3x^2 = 18x
uysha [10]

(0,0) and (6,0)

First we subtract 18x from both sides

3x²-18x=0

Factor out a 3x

3x(x-6)=0

This means that x is either 0 or 6
