What is the area of the rectangle, in square centimeters. I AM TIMED

60

Step-by-step explanation:

For rectangle

length x width = area

length + width x 2= perimeter

for square:

length/width x 4 = perimeter

length x width = area

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

(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
