1. A.Complementary
2. C. Neither
3. B. Supplementary
4. Z= 128
Why?
The angles for #1 equal 90. For 2 it is not either option. 3 equals 180 and for 4 is 180-52 and you get 128

Can I pls have a brainliest?
what is the explicit formula
Answers
Answer:
a(n) = 13 - 2n
Step-by-step explanation:
The explicit formula variables are a(n) = a(1) + d (n - 1). The a(1) is your number you started out with, and the d is the common difference. From the recursive formula example, you see that your first number is 11 and your difference is -2.
1. Plug the numbers into the equation : a(n) = 11 - 2 (n - 1)
2. Distribute: a(n) = 11 - 2n + 2
3. Add like terms: a(n) = 13 - 2n
If you want to double check, you can plug 1 into n and see if you get 11. I did this, and I did so it should be correct. Hope this made sense! Have a great day :)

Answer:
AY = 4.8YD = 2.4Step-by-step explanation:
Corresponding sides of the triangles are ...
ΔFUN . . . ΔDAY
UF = 10 . . . AD = 6
FN = 4 . . . DY
NU = 8 . . . YA
Corresponding sides are proportional, so we have ...
DY/4 = AD/UF = 6/10
DY = 4(0.6) = 2.4
and
YA/8 = 6/10
YA = 8(0.6) = 4.8
The side lengths are ...
AY = 4.8, YD = 2.4

The circumference of the hub cap of a tire is 73.79 centimeters. Find the area of this hub cap. Use 3.14 for π. Use pencil and paper. If the circumference of the hub cap were smaller, explain how this would change the area of the hub cap.
The area of this hub cap is about __ square centimeters.
Answers
Answer:
433.5 cm²
Step-by-step explanation:
The formula for circumference is C = 2πr, where r is the radius.
Here, C = 2πr = 73.79 cm. Solving this for the radius, r, we get:
73.79 cm
r = ---------------- = 11.75 cm
2(3.14)
Then the area of the hubcap is A = πr², or, in this case,
A = 3.14(11.75 cm)² = 433.5 cm²
Answer:
simple answer (and rounded for u) = 434 centimeters squared! hope it helps peeps
