No, these do not always forma unique triangles because it depends on what size your sides are because if you have 3 sides of the same length then that’s a equilateral and if you have two sides of the same length and one side that’s not then that would be an Isosceles triangle and if you had no sides of the same length then that would be a scalene triangle.
You would times 20 and 15 to get 300 and then divide 300 by 25 to get 12
Answer:
x = 47
Step-by-step explanation:
86° and 2x° are supplementary angles, which means that added together they should equal 180° (which is a line). Aka
86 + 2x = 180 (Let's solve for x) (subtract both sides by 86 to get x on one side)
2x = 94 (divide both sides by 2 to get x by itself)
x = 47
Answer:
f(x) = -x + 3
Step-by-step explanation:
To flip it over the y-axis, just make all your x-values negative.
y(x) = x + 3
f(x) = y(-x) = (-x) + 3 = -x + 3
