What is the negation of the following statement?
At least one angle is acute.

A:At least one angle is not acute.

B:None of the angles are acute.

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

whatvare the choices

step-by-step explanation:

ca = ec

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two
