We know that \sin(45)=\cos(45) and this is the only point when sin and cos are equal lengths. Because both \sin(45),\cos(45)=\dfrac{\sqrt{2}}{2}

Now if the sin of 30° is a half that would mean that cos of 60° is also a half.

Hope this helps.

Sarah has 25 coins that are dimes and nickels. Together they total $2.00. How many of each type does she have?
Ivanshal [37]

Answer:

15 dimes and 10 nickels

Step-by-step explanation:

15 dimes because 15 multiplied by 10 cents is $1.50

10 nickels because 10 multiplied by 5 cents is $0.50

15 x 0.10 = 1.50         10 x 0.50 = 0.50

0.50 + 1.50 = 2.00
