Answer:
Alt Ext ∠s, Then
m∠4 = 105, m∠5 = 105
Step-by-step explanation:
m∠4 and m∠5 are alternate exterior angles. Alternate exterior angles are equal.
m∠4 = m∠5
30x + 45 = 60x - 15
45 + 15 = 60x - 30x
60 = 30x
x = 60 / 30
x = 2
m∠4 = 30x +45
= 30 ( 2 ) + 45
= 60 + 45
m∠4 = 105
m∠5 = 60x - 15
= 60 ( 2 ) - 15
= 120 - 15
m∠5 = 105
