It’s 40 degrees
I subtracted 180 minus the 150 and got 30 then addd 110 and 30 and got 140 then substractef that from 180 and got 40
Answer:
32.1
Step-by-step explanation:
d=sqrt ((x2-x1)^2+(y2-y1)^2 )
Find length of AB
d=sqrt((2-(-4))^2+(0-5)^2)
d=sqrt(6^2+(-5)^2)
d=sqrt(36+25)
d=sqrt(61)
d= around 7.8
Find length of BC
d=sqrt((4-(-4))^2+(10-5)^2)
d=sqrt(8^2+5^2)
d=sqrt(64+25)
d=sqrt(89)
d= around 9.4
Find length CD
d=sqrt((8-4)^2+(7-10)^2)
d=sqrt(4^2+(-3)^2)
d=sqrt(16+9)
d=sqrt(25)
d=5
Find length DE
d=sqrt((4-8)^2+(5-7)^2)
d=sqrt((-4)^2+(-2)^2)
d=sqrt(16+4)
d=sqrt(20)
d= around 4.5
Find length EA
d=sqrt ((4-2)^2+(5-0)^2 )
d=sqrt(2^2+5^2)
d=sqrt(4+25)
d=sqrt(29)
d= around 5.4
P=7.8+9.4+5+4.5+5.4
P=32.1
1. -7 + 9= -9 + 7 is false
2. Is 4x - 3 = 19 is open, because this could be a valid equation.
3. 16 = 4x - 4
So, 16+4=4x; 4x=20; x=20/4; x=5..... option C is the correct one.
4. length of the classroom is 2.4 times its width.
given length = 42 in, and since length = 2.4 times width, width = 42/2.4,
hence option A) 17.5 in is correct
5. x - 3 = 10
x = 10+3 =13
Option B is the right one.
