noah drew an equilateral triangle with sides of length 5 inches. he wants to increase the length of each side by x inches so the triangle is still equilateral and has a perimeter of 20 inches.

answer: they are supplementary angles

step-by-step explanation: 161+19=180. supplementary angles equal 180 degrees

graph #4 (last graph) depict the function   f(x)= -m(x-d)^1/5 i

step-by-step explanation:

we know that

m=slope

but in this function slope is -m that means slope is decreasing and it is decreasing by 1/5 points down the x-axis.

which is shown in graph four

a decreasing slope down x-axis by 1/5 points.

hence 4th graph is the right option for this.
