An acute angle can have all of the following measures except 89 45 10 0

0 is not an acute angle.

Step-by-step explanation:

If the measurement of an angle is between 0 and 90 degrees then we called  it an acute angle. It means acute angle is greater than 0 and less than 90 degrees.

Mathematically, we have

0° < Acute angle < 90°

Among all the given options, the angle 89, 45 and 10 is in between 0 and 90 degrees. Hence, these are acute angle.

Thus, 0 is not an acute angle.

1: -2 3/4, -2 1/2, -14, 0, 3, 8 1/3

2: -4, -3, -2 1/2, -2 1/4, 3 1/4,

step-by-step explanation:

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
