I remember this but I dead forgot how to do it
You have to dividers then multiply then add then subtracts the 2 from the r
Answer:
a=6
Step-by-step explanation:
write the equation as y=mx+b
y=-5/3x+b
solve for b
1=-5/3*-3+b
1-5=b
b=-4
Plug in -14 and solve for x
-14=-5/3x-4
-10=-5/3x
30/5=x
x=6 (x is basically a because a is the x coordinate)
Answer:
15 sides
Step-by-step explanation:
Always the sum of interior angle and exterior angle = 180
Let the exterior angle = x
Interior angle = 6.5 *x = 6.5x
x + 6.5x = 180
7.5x = 180
x = 180/7.5
x = 24
Exterior angle = 24°
Sum of exterior angles of any polygon = 360
number of side = Sum of exterior angles ÷ measure of each exterior angle
= 360 ÷ 24
= 15
See the suggested solution in the attachment.
