Answer:
B= 90
C= 80
D= 100
Step-by-step explanation:
So let’s start with the bottom angles.
We know that the adjacent angles in a parallelogram add up to 180° so our equation would be
. So let’s simplify it b and b are both the same variables so we will get 2b and -10 + 10 is 0 so we get the following equation
.
So now we divide 180 and 2 and we get 90 as b.
So one side will be 100 because of the +10 and the other 90 because of the -10.
Now for the next side.

So we know that b+10 is adjacent to c so 180-100 is 80, so 80 is c.
Now for d.
b-10 is 80 so 180-80 is 100, so d is 100.
Answer:
24xz + 28yz
Step-by-step explanation:
4z(6x + 7y) ← multiply each term in the parenthesis by 4z
= 24xz + 28yz
Answer:
259200 seconds
The conversion factor from days to seconds is 86400, which means that 1 day is equal to 86400 seconds:
1 d = 86400 s
To convert 3 days into seconds we have to multiply 3 by the conversion factor in order to get the time amount from days to seconds. We can also form a simple proportion to calculate the result:
1 d → 86400 s
3 d → T(s)
Solve the above proportion to obtain the time T in seconds:
T(s) = 3 d × 86400 s
T(s) = 259200 s
The final result is:
3 d → 259200 s
We conclude that 3 days is equivalent to 259200 seconds:
3 days = 259200 seconds
