Good evening ,
_______________
2(7) + 5(1) + 3(-3) = 10
3(7) - (1) + 4(-3) = 8
5(7) - 2(1) + 7(-3) = 12
Then (7,1,-3) is a solution to system

Answer:
option 2.
m1 = 147° m2 = 80° m3 = 148°
Step-by-step explanation:
a flat angle has 180 °
m1 + 33 = 180
m1 = 180 - 33
m1 = 147
47 + 33 + x = 180
x = 180 - 47 - 33
x = 100
as they are two crossed lines the angle is reflected from the opposite side
48 + 100 + y = 180
y = 180 -100 - 48
y = 32°
180 = m3 + 32
m3 = 180 - 32
m3 = 148
With the same principle as the previous one we know that the angle of a turn is 360 °, if we subtract the 2 known angles and divide it by 2 we will obtain the missing angle
m2 * 2 = 360 - 100*2
m2 = 160 / 2
m2 = 80

L= 78 si P=256
P=2L+2W w e width(latime)
256=2*78+2w
256=156+2w
256-156=2 w
100=2w
w=50
