The law of sines can be used to find the missing side lengths.
... RP = sin(60°)/sin(45°)·10 = 10√(3/2) ≈ 12.247
... PS = sin(75°)/sin(45°)·10 ≈ 13.660
Then the perimeter is
... perimeter = RS + RP + PS
... = 10 + 12.247 + 13.660 ≈ 35.91 . . . .units
Answer:
Option a is correct -- 
Step-by-step explanation:
If we put infinity directly into the expression we get ∞ + ∞ expression. In order to circumvent it we divide both numerator and denominator with the greatest exponent.

Divide each term by n³


No, the decimal will be over four places
35%=35/100=0.35
0.35x=42
divide both sides by 0.35
x=120
35% of 120 is 42
Answer=120
