Question

What is the answer to this question?

Answer 1

A = 139 degrees
G = 41 degrees

Answer 2

A = 139°

G = 41°

Explanation:

Measure of D = 139°

• Given that, X|| Y

Then

• Alternate angle theorem (Remember that "Z" Theorem?)

< D = < H (By simple theorem above![Alt <s])

<H = 139°

Also <H = <A[Vertically opposite angles]

<A = 139°

We know by co-interior < theorem,[X||Y]

• <H +<G = 180°
• <G = 180° - <H = 180° - 139°
• <G = 41°
