Answer:
m3 should be 70°
all internal angles of a triangle add up to 180
180-35-75 = 70
Yes this is equal because 3v+v is 4v and if you divide 12v by 3 you also get 4v
<span>-4x + y = -25 y = 4x - 25
-6x - 6y = 0 </span>
-6x - 6(4x - 25) = 0
-6x - 24x + 150 = 0
-30x + 150 = 0
-30x = -150
x = 5
y = 4(5) - 25
y = 20 - 25
y = -5
(5, -5)
