Please solve asap I don’t know how do this question

Answer:

  x = 9

Step-by-step explanation:

All of the right triangles in the figure are similar. That means ratios of corresponding sides are the same.

The two sides marked with numerical values have lengths 5 and 2√5 ≈ 4.47. The remainder of x, which is (x-5), will be shorter than either of the other two marked lengths. This means we can write the ratio of short side to long side of the two smaller triangles as ...

  short side / long side = (2√5)/5 = (x-5)/(2√5)

Cross-multiplying gives ...

  20 = 5(x -5)

  4 = x -5 . . . . . divide by 5

  9 = x . . . . . . . add 5

_____

<em>Additional comment</em>

In this geometry, as we have seen above, the square of the altitude ((2√5)²=20) is the product of the lengths of the segments of the hypotenuse (5×4=20). There are two other "geometric mean" relationships in a triangle like this, involving the legs of the largest triangle. They all arise from the similarity of the triangles.

Given the figure below, find the values of x and z.<br> X=<br> Z=<br> (11x - 93)<br> H<br> 116<br> X
Marrrta [24]

Answer:

x = 19

z = 64

Step-by-step explanation:

Angles (11x - 93)° and 116° are vertical angles, so their measures are equal.

11x - 93 = 116

11x = 209

x = 19

Angles z° and 116° are a linear pair, so they are supplementary, and their measures have a sum of 180°

z + 116 = 180

z = 64

The volume of an oblique pyramid with a square base is V units3 and the height is h units.
TiliK225 [7]
The volume of a quadrangular base pyramid is:
 V = (1/3) * (Ab) * (h)
 Where,
 Ab: base area
 h: height
 Clearing the area of the base we have:
 Ab = (3 * V) / (h)
 Answer:
 
An expression that represents the area of the base of the pyramid is:
 
A) 3v / h units
