∡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°.
<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!

1/ we make -3*and and we have y=-1 and we replaced to have x=6
2/ any answer x=(7y+3)÷2
If we change answer of x in the second equation we get -7y-3+7y=-3
3/ x=-4+2y we change it in the second equation and we get y =1 if replace it in the first we have x=-2
4/ B=10 and C=16
5/ a= false
b=true
c=true
d=true
Answer:
Improper Fraction: 20/3 yards
Mixed number: 6 2/3
Step-by-step explanation:
If 1 dress needed 5/6 yards to complete
then 8 dress needed
8 x 5/6 yards
which is 20/3 yards
I hope this helps
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.
