m=4, therefore your slope is 4.
Steps:
m=y2-y1/x2-x1
Substitute values in:
m= 9-(-7)/3-(-1)
Then just simplify. :)

Permutations are for lists (order matters) and Combinations are for groups (order doesnt matter)
160+100+180+60=500
180/500=0.36=36%
50x36%=18
That's your answer lovely~

Answer:
36°
Step-by-step explanation:
Each exterior angle is 360°/5 = 72°. This is the base angle of the isosceles triangle formed by drawing a line opposite angle y at the corners of the pentagons.
The angle y is ...
y = 180° -2(72°)
y = 36°
A) By Pythagoras' Theorem x^2 = 13^2 - 5^2 where x = length of the other leg. x^2 = 169 - 25 = 144 so x = 12. cms.
b) perimeter = 5 + 12 + 13 = 30 cms
c) Area of triangle = product of the 2 legs = 5*12 = 60 cm^2.
