Answer: 
Step-by-step explanation:
It is important to remember the following:

In this case you can observe in the figure that "x" is an Angle formed by two chords, therefore, you can find its value applying the formula.
Therefore, the value of "x" is this:

Answer:
Just multiply
length x width = area
94 x 50 = 4700
Step-by-step explanation:
Lets remember the property "alternative-interior angles" when we have parallels lines:
Given two paralles lines, the following is true:
In our question, we have:
We know that the angles J + P + K=180
So, the triangles have all the angles the same, so they are similar by angle-angle-angle, and they have one side congruent, AC=CD, so the triangles are congruents.
Ghi=j
h/gi=j/gi
h=j/gi
the sign "/" means divide by
