Step-by-step explanation:

There are 5 points around the circle. A circle is 360 degrees

360/5 =72

There are 72 degrees between points

ABC has 2 sections between

2*72 = 144

m <ABC = 144

ABD  has 3 sections between

3*72 = 216

m <ABC = 216

Assuming that you can draw the lines

We know m<ED

It has one section so it is 72

m< AFC = 1/2(mABC +m<ED)

m< AFC = 1/2(144+72)

               =1/2(216)

               =108

a) 108°

b) 72°

c) 108°

Step-by-step explanation:

Arc ABC = (⅖) × 360 = 144°

Angle ABC = (360-144)/2 = 108°

Arc ABD = (⅗) × 360 = 216°

Angle ABD = (360-216)/2 = 72°

Angle AFC = Angle ABC = 108°

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.
