The equation for l is y = 4.
The equation for p is x = -4.
The equation for m is y = -2x + 4.
The equation for n is y = x - 1.
Answer:
16
Step-by-step explanation:
First. for you to find the radius of the circle you must know the steps/formula to find the area.
the radius of the circle times pie 3.14.
so x times 3.14 will give you 50.24
the opposite of multiplication is division
so 50.24 divided by 3.14 is 16
because 16 times 3.14 is 50.24 sq in.
diagonal is square root of A^2+b^2
so C is the correct answer
50.625 is the answer You should round it though
Answer:
On the diagram, construct lines BY, XY and DY.
Now, consider triangles ΔXBY and ΔXDY. We can say that these triangles are congruent by the SAS postulate (they share side XY, XY bisects ∠BYD so ∠BYX=∠DYX, and BY=DY=radius). If they're congruent, their sides are the same so BX=DX.
BX=DX
AB+radius = CD +radius
AB=CD
