What is surface area of the figure below, in square inches?

Surface area is 310

Step-by-step explanation:

To find the surface area, you must find the area of all shapes (sides/surfaces) and add them together.

the discriminant is 64 + 4*1*12 = 112

this is prime.

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
