Referring to the diagram at the right, ABC = 4x + 30, ABD = 5x + 10, and DBC = 3x - 20 Find x. Find ABC. Find ABD show your work!

ABD+DBC=ABC

Step-by-step explanation:

5X+10+3X-20=4X+30

X=10

To get abd substitute into 5x +10

5{10}+10

50+10

60

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,
