Answer:
V= 105cm^3
Step-by-step explanation:
V=volume
(1/3)V+40=(5/7)V
(5/7)V-(1/3)V=40
(15/21)V-(7/21)V=40
(8/21)V=40
(21/8)(8/21)V=(21/8)(40
V=21*5
V=105 cm3
(1/3)(105)=35, 35+40=75, 75/105=15/21=5/7
It’s 180-135 which equals 45 so it is 45 degrees for X
⛅️ = 10
❄️= 5
Unfortunately that’s all I can offer because I don’t understand what the + + and ❄️ x means
