Answer:
45 members are in the choir.
Step-by-step explanation:
Set up an equation:
Variable x = boys
3/6 = x/30
Cross multiply:
3 × 30 = 6 × x
90 = 6x
Divide both sides by 6:
15 = x
There are 15 boys.
To find the number of members in the choir, add the number of boys and girls:
30 + 15 = 45
Answer:
A.) NM= x
C.) LM = x√2
E.) tan (45°) = 1
Step-by-step explanation:
If the legs are both x, then the hypotenuse is equal to 
Therefore, LM= is correct and MN= x
