Answer:

∠1 ≅ ∠2 by the Alternate Interior Angles Theorem

m∠3 = 130° due to the Congruent Supplements Theorem

Step-by-step explanation:

The Alternate Interior Angles Theorem State that if two parallel lines are split by a transversal, then the pairs of alternate interior angles are congruent.

In this case, the measure of ∠1 is equal to 180° - m∠3 due to the Congruent Supplements Theorem. So, m∠1 is equal to 50°, which also means m∠2 is also 50°.

Answer:

Step-by-step explanation:

i assume x+y=6(1/2)=\frac{13}{2}

$\frac{5}{8}=\frac{x}{y}=\frac{x}{\frac{13}{2}-x}=\frac{2x}{13-2x}\\65-10x=16x \\26 x=65\\2x=5\\x=\frac{5}{2}\\y=\frac{13}{2}-\frac{5}{2}=\frac{8}{2}=4$
