Answer:
Step-by-step explanation:
m ∠XOY = m ∠WOV
so, m XY = m WV --- (i)
{ If angle subtended by two arcs at the center are equal, then length of arc are equal}
m YZ = m ZW ------- (ii) {given}
Add (i) and (ii)
XY + YZ = WV + ZW
XZ = ZV
Hence proved.

Answer:
C, D, B
Step-by-step explanation:
the mode is if a number is repeated more than one time
EX. 15, 23, 15, 23, 15
C because 15 is repeated 3 times and 19 is too.
D because 42 is repeated 2 times and so is 18.
B because 87 is repeated 2 times and 32 is too.
Answer:O_O
Step-by-step explanation:
Answer:
Step-by-step explanation:
Formula
h = k/temp
Givens
h = 4 hours
t = 45 degrees
Solution
3 = k / 45 Multiply both sides by 45
3*45 = k
k = 135
Problem
what happens when h = 4 hours?
h = 4
k = 135
temp = ?
4 = 135 / temp Multiply both sides by temp
4temp = 135 Divide by 4
temp = 135 / 4
temp = 33.75
Note that as the time went up, the temperature came down
