Answer:
About 6 inches tall.
Step-by-step explanation:
One book has a thickness of 2
inches.
Another book has a thickness of 3.56 inches
Converting 2
inches to decimals will give; 2.4285714286 inches
If the books are stacked together, they become 2.4285714286 inches + 3.56 inches = 5.988571429 inches tall or about 6 inches tall (answer rounded up to nearest whole number).

Z=10 because the opposite side is 50 degrees so the 5z=50
If you solve, z=10
