Evaluate the geometric series. Round to the nearest hundredth. Please help me!!!

62.34

Step-by-step explanation:

Substitute n = 0 to n = 5 into the expression and sum the terms, that is

3 [  + + + + + ]

= 3 [ 1 + + + + + ]

= 3( )

= 3 × 20.781

= 62.34 ( to the nearest hundredth )

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
