Second one
Step-by-step explanation:
Answer:
C = 80
Step-by-step explanation:
A cyclic quadrilateral is one where all 4 vertices touch the circumference of a circle.
It has 1 interesting property that should concern you: <B + <D = 180 degrees.
3x - 59 + 2x - 1 = 180 Combine like terms
5x - 60 = 180 Add 60 to both sides.
5x = 180 + 60
5x = 240
x = 240/5
x = 48
Now go to 2x + 4.
x = 48
A = 2*48 + 4
A = 96 + 4
A = 100
So C = 180 - 100
C = 80
Answer:
36hr 16min
Step-by-step explanation:
1pool/17hr - 1pool/32hr = 1 pool/xhr
1/17 - 1/32 = 1/x
Use common denomminator of 17*32 = 544
32/544 - 17/544 = 1/x
15/544 = 1/x
x = 544/15
x = 36 4/15 hr
x = 36hr 16min
-3(x+3)=-3(x+1)-5
-3x-9=-3x-3-5
-3x-9=-3x-8
