Answer:

Question 1

since triangles are similar

angle B = angle D

8x + 16 = 120

x = 13

Question 2

Ttiangles are similar

therefore, sides are in ratio

AB ÷ XY = BC ÷ YZ = AC ÷ XZ

substituting all values we get

BC = 22

BC = 22AC = 16

If a parallelogram has diagonals that are perpendicular bisectors of each other, what is the most descriptive name for it?

Feliz [49]

Both a rhombus and a rectangle have diagonals that are perpendicular bisectors, but the ones formed in a square are all congruent, so that is probably the most descriptive one.

Ok guys my friend is telling me that i am doing this problem wrong 4^4+1/2=256.5 and he is tell me that it is 16.5 am i right or

Alexxx [7]

Simplify 4^4 to 256

256 + 1/2 = 256.5

Simplify 256 + 1/2 to 513/2

513/2 = 256.5

Since both sides equal, there are infinitely many solutions.

What is the common ratio between successive terms in the sequence<br> 2,4,8,-16, 32, 64,

marysya [2.9K]

Answer: The sequence does not have common ratio.

Step-by-step explanation:

By definition, a sequence with a constant ratio (common ratio) between terms is called a "Geometric sequence". In order to find the common ratio, it is necessary to divide any term in the sequence by the previous term.

In this case, given the sequence:

$2,4,8,-16, 32, 64,$

We get:

$4\div2=2\\\\8\div4=2\\\\-16\div8=-2\\\\32\div(-16)=-2\\\\64\div32=2$

Since the ratios between the terms are not constant, we can conclude that <em>the sequence does not have common ratio.</em>
