The sides of triangle abc are 4.5 feet, 7.5 feet, and 9 feet long. the area is about 17 square feet. explain how to use the area of triangle abc to find the area of a triangle def with side lengths 6 feet, 10 feet, and 12 feet.

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15

the answer is -6

step-by-step explanation:

the answer is -6 because its next to the variable m
