Plz hurry part a:

find the measure of the following angles:

< 1

< 2

< 3.

show your work to justify your answers. earn up to 1 point for each missing angle with the correct answer and work shown.

part b:

answer the following question in 1-2 complete sentences. how is the measure of < 1 and the measure of < 2 related to the exterior 123° angle?

Step-by-step explanation:

(A) From the given figure, we have

(Linear pair)

⇒

⇒

Thus, the measure of is .

Also, using the angle sum property in the given triangle, we get

⇒

⇒

⇒

Thus, the measure of is .

And,

⇒

⇒

Thus, the measure of is .

(B) Exterior angle theorem states that the exterior angle is equal to the sum of the two interior angles, thus from the given figure, we have

Therefore, the relationship between the measure of and   to exterior angle is .

just find the gcf and solve the gcf's until you get each answer i have a really good feeling somethings missing xd (like the dimensions of the fence) *cough *cough *hint *hint
