PLEASE PLEASE solve step by step !!!!!!! I will mark Brianliest correct answer !!!

Answer:
m<3 = 70 and m<4 = 110
Step-by-step explanation:
<3 and <4 are vertical angles so they add up to 180
(3y + 7) + (5y + 5) = 180
(3y + 5y) + (7 + 5) = 180
8y + 12 = 180
-12 -12
8y = 168
/8 /8
y = 21
find the angle measures:
3(21) + 7
63 + 7
70
5(21) + 5
105 + 5
110
