Why are the solutions to the proportions 40/80 = to x/10 and x/40= 10/8 the same
Daniel [21]

Answer:

In 2 expression the value of x  is different

Step-by-step explanation:

It is given that,

40/80 = to x/10 and x/40= 10/8

<u>To find the value of 40/80 = to x/10</u>

40/80 = x/10

x = (40*10)/80

x = 5

<u>To find the value of x/40= 10/8</u>

x/40 = 10/8

x = (40*10)/8

x = 50

From the given results we get the value of x is different.

The following angles in a convex quadrilateral Angle A= 56.1 degrees Angle B= 99.4 degrees Angle C= 78.2 degrees What is the mea
Contact [7]

Hello,

The sum of angles in a quadrilateral is 360°.

56,1° + 99,4° + 78,2° + x = 360°

233,7° + x = 360°

x = 360° - 233,7° = 126,3°

Bye :)
