The answer is 91 and the property used is the Identity Property of Addition.
If we draw a perpendicular line from one of the vertices of the triangle we get 2 right angled triangles each with altitude 9 ins and vertex angle = 30 degrees. So:-
cos 30 = 9 /h where h = one of the sides of the equilateral triangle
h = 9 / cos 30 = 10.392 inches
Therefore the perimeter of the triangle = 3 * 10.392 = 31.1769 ins
Answer is 31.18 inches to the nearest hundredth.
-5 Subtract 8 from -12 and divide -20 by 4 and get -5
x=1/2

Answer:
1. slanting upward because the slope is positive one.
2. A: 3/4 B: 4/-3
3. A: 3 B: y=3x-10
1. (-2-7)/(-4-5) = -9/-9 = 1
2. A: (7-4)/(7-3) = 3/4
B: (8-0)/(-6-0) = 8/-6 = 4/-3
3. find the slope first so (4-1)/(2-1)= 3/1. then you plug in point C to find the y intercept so y=mx+b would be 2=3(4)+b which makes it so b is -10. the new equation would be y=3x-10
