0 Which of the following number lines shows the correct sum of the number above and ?
HHH
A
1
B
O
2
C
0

B

Step-by-step explanation:

because when you are looking at 3/2 it is equivilent to 1.5 or 1 1/2 and c is equivalent to 1 1/2

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.
