Answer:
4(x-5)=92
4x-20=92
4x=92+20 (as we shifted - 20 to other side, it becomes +)
4x=112
x=112/4
x=28
Therefore the x=28
Hey there!
These triangles are similar by SAS. This is because the side with a length of 10 is the first side, then the angle is the 90 degree angle created by the perpendicular bisector. And the last side is proportional by a relationship of AG/GB = TG/AG.
Therefore, the triangles are similar by SAS, or option C.
Hope this helps!! :)
Since a pentagon has 5 sides, you would divide the perimeter by the number of sides.
641.5/5 = 128.3cm
Therefore, the length of one side of the pentagon is 128.3cm.
Answer:
x = 20
Step-by-step explanation:
Each side would be 60. 60/3 would be 20. So x = 20
We have the function:
A turning point happens when the function reaches a maximum or a minimum.
In that points the value of the first derivative of the function is equal to 0.
So we can find the turning points by finding the first derivative and equal to zero:
