Answer:
x = 6, z = 5.66 to nearest hundredth.
y = 90 degrees.
Step-by-step explanation:
From the chord intersection theorem 12*4 = 8 * x
So x = 6.
By the tangent / chord theorem:
z^2 = 2 * (12+4)
z^2 = 32
z = 5.66.
I'm not 100% sure of the value of angle y but I think its
1/2(100 + 80) = 90 degrees.
I'll try and check that out.
Yes that is right.
Answer:
yes use this to your advangtage yessss
2x+3(2x-4y)+8y-2
2x+6x-12y+8y-2
8x-12y+8y-2
8x-4y-2
Answer:
0.3175
Step-by-step explanation:
z=-1.25 from table is .1056
z=.80 from table is .7881
subtract from each other =.6825
Subtract from the whole is 1-.6825=0.3175
Is it asking how many she began with before she sold them? If so, then I think at the beginning she started out with 40. I think she had 40 because she sold half, and when you divide 40 by 2 it divides perfectly giving you 20. Then add 16 to that and you come out with 36.
