Question

<B is a comp. of <A.
<C is a supp. of <B.

<D is a supp. of <C.

<E is a comp. of <D.

<F is a comp. of <E.

<G is a supp. of <F.

 

Then <G=_?__

Answer 1

B = 90 - A

B = 180 - C

90 - A =180 - C

-A = 90 - C

A = 90 + C, C = 180 - D

A = 90 + 180 - D

A = 270 - D, D = 90 - E

A = 270 - (90 - E)

A = 180 + E, E = 90 - F

A = 180 + 90 - F

A = 270 - F, F = 180 - G

A = 270 - (180 - G)

A = 90 + G

A - 90 = G ??
