Answer:
√2
Step-by-step explanation:
Angle ( θ ) = 45
Hypotenuse side = 2
Opposite side = x
Formula : -
sin θ = Opposite side / Hypotenuse side
Note :
The value of sin 45 = 1/√2
sin 45 = x/2
1/√2 = x/2
Cross multiply,
x*√2 = 2*1
x√2 = 2
2 can be simplified as √2 * √2
x√2 = √2*√2
Divide √2 on both sides,
x = √2

Answer:
12 sapphires
Step-by-step explanation:
Let's call the number of sapphires x. This means the number of rubies is the total number of gems minus x, or 17-x.
# of Sapphires: x
# of Rubies:17-x
A sapphire is worth 5 (gold coins) each, and a ruby is worth 8.
We also know the total amount of money is 100 coins, so
5*x+8*(17-x)=100
5x+136-8x=100
-3x=-36
x=12
Remember:
# of Sapphires: x
# of Rubies:17-x
...so Lara found 12 sapphires and 17-12=5 rubies.
