You are given that that m∠1 = 106° and m∠2 = 50° and PQ║JK
Since PQ and JK are parallel, then because of the alternate interior angles theorem, ∠5 = ∠2, so ∠5 = 50° as well.
∠1 and ∠8 are corresponding angles so therefore they are equivalent and ∠8 = 106°.
∠4 and ∠8 are corresponding so they are equivalent as well and ∠4 = 106°.
∠3 is alternate interior angles with ∠5 which we already found, so they are equivalent and ∠3 = 50°
∠7 and ∠8 are vertical angles so ∠7 = ∠8. We already found ∠8, it is 106°. Therefore ∠7 = 106°.
In summary,
∠4 = 106° because of corresponding angles with ∠8
∠3 = 50° because of alternate interior angles with ∠5
∠5 = 50° because of alternate interior angles with ∠3
∠8 = 106° because of corresponding angles with ∠1
∠7 = 106° because of vertical angles with ∠8
Hope this helps! ^-^
y= mx/z
You isolate the variable by dividing each side by factors that don't contain the variable, which gives you the answer as "mx" as the numerator and "Z" as the denominator.
