Question

in the figure below, m ∠1=39°. find m ∠2, m ∠3, and m ∠4.

m ∠2 = °
m ∠3 = °
m ∠4 = °

Explanation:

Step1: Find m∠2 (vertical to ∠1)

Vertical angles are equal, so $m\angle2 = m\angle1 = 39^\circ$.

Step2: Find m∠3 (supplementary to ∠1)

∠1 + ∠3 = 180°, so $m\angle3 = 180^\circ - 39^\circ = 141^\circ$.

Step3: Find m∠4 (vertical to ∠3)

Vertical angles are equal, so $m\angle4 = m\angle3 = 141^\circ$.

Answer:

$m\angle2 = 39^\circ$, $m\angle3 = 141^\circ$, $m\angle4 = 141^\circ$
