Find the missing variable for a parallelogram: A=64 h= b= 12.6
gizmo_the_mogwai [7]

Answer: h= 5.08

Step-by-step explanation:

In a parallelogram , the formula to find the area of the parallelogram is given by :-

A=b\times h , where b is the base and h is the height of the parallelogram.

Given : A=64                      h=?                     b= 12.6

Substitute these values in the above formula , we get

64=12.6\times h

Divide both sides by 12.6 , we get

h=\dfrac{64}{12.6}=5.07936507937\approx5.08

∴ The missing variable : h= 5.08

A right triangle ABC is shown below:
barxatty [35]
The answer is:  "4" .
______________________________________________________
<u>Note</u>:  The question asks for a whole number.

"The area of the triangle above will equal one half of a rectangle that is 5 units long and <u>  4  </u><u /> units wide.  (Input only whole numbers, such as 8.).
______________________________________________________
<u>Note</u>:  The diagram shows a "right triangle" ; which would be "one-half" of a rectangle, with units of "length" being "5 units" (as mentioned in this very question prompt;  and a width of "4" units (as shown in the diagram;  hence the answer is "4" units). 

Furthermore, the formula/equation for the area, "A" , of a triangle is: 


A = (1/2) * b * h ; 

that is: 

Area = (1/2) * (base length) * (perpendicular height).
_________________________________________________
As such, the answer, "4" (units) makes sense.

What is the value of x? 45° 2 (2x - 5) &gt; n​
Vladimir [108]

Answer:

70 degrees

Step-by-step explanation:

Find the diagram attached

The sum of the angles is supplementary that is

45 + 2x- 5 = 180

2x + 40 = 180

2x = 180 - 40

2x = 140

x = 140/2

x = 70

Hence the value of x is 70 degrees
