Answer:
Concept: Mathematical Analysis
- 2 friends share 56
- 5- 10 dollar bills and 6- one dollar
- We split the bills in half to equate equal change.
- Hence 5 bills ÷2= 2.5 or 25 dollars
- 6 bills÷2= 3 or 3 dollars
- You need to make change for the 10 dollars, break a bill into 5's

Have a great day :)
Answer:
a = -2 z^-3 c^6
Step-by-step explanation:
equations are given as
a = 2b^3 .....1 and
b = -1/ z c^-2 .....2
put the value of b in eq 1
a = 2(-1/z c^-2)^3
a = 2(-1/z^3 c^-6)
or a = -2 z^-3 c^6
General rule: The angles on a straight line total 180°
The right angle equates to 90°
Since that angle is half of our desired angle, it must mean that 2x + x = 90°
breaking this down, we get 3x = 90° which can be divided to make x = 30°
