. If a = 120°, find the measure of angles b, c and d.<br> Explain your reasoning.
Alchen [17]
∡b is a vertical angle to ∡a and therefore a twin, and we know that ∡a = 120°, thus since ∡b = ∡a, ∡b = 120° as well.

a full circle has a total of 360°, ∡d and ∡c are vertical angles, namely two angles across from each other at a junction, and therefore ∡d = ∡c.

∡a + ∡b is 120° + 120° thus 240°, since a circle has a total of 360°, 360 - 240 = 120, so the other two angles pick up that slack and divide it among each other evenly, 120/2 = 60, so ∡d = ∡c = 60°.

NCr/nPr=r!<br><br> give proof.
Sergio [31]
<span>It's 1/r! 

nCr = n! / r!(n-r)! 
nPr = n! / (n-r)! 

If you divide the two you'd have: 

n! / r! (n-r)! * (n-r)! / n! = 1/r!

The number z and −1.9 are additive inverses.
tia_tia [17]

Additive inverses are numbers that add up to zero, such as 1 and -1. Z is the additive inverse of -1/9, so z is 1.9.

1.9 + -1.9 =0.

Drag the -1.9 icon to just one mark to the right of -2 on the number line, since each dash equals 0.1.  Drag z to just one mark to the left of 2 on the number line.The sum will be zero, so drag the sum icon to 0 on the number line.
