Answer: 85 degrees
Step-by-step explanation: 20x+5+24x-1=180
44x+4=180
-4 -4
44x=176
division property of equality x=4
20(4)+5=
80+5= 85 degrees
Answer:
Expression for Perimeter: 6x + 6
x = 12 cm
Verify A = 360:
2(12) x (12+3) = 360
24 x 15 = 360
360 = 360
Step-by-step explanation:
4( 40 - 30)
subtract 30 from 40 is expressed as 40 - 30
then multiply by 4 is expressed as 4 × (40 - 30) or 4(40 - 30) = 40
Answer: A.71
Step-by-step explanation: 1.set up the equation
2. 4n-18+n+9=151-5n
3.combine like terms -> 5n-9=151-5n
4.solve for n
5.10n=160
n=16
now you have to plug 16 in for n in order to get the remote exterior angle.
151-5(16)
151-80
71°
Answer:
the center (0.0)
radius length {5
=x^2+y^2=25
6^2+8^2
36+64
100
which is greater than 25
so Itli outside of circle
