Find the measure of x. 10
х
20°
x = [? ]
Round your answer to the nearest hundredth.

x ≈ 3.42

Step-by-step explanation:

Using the sine ratio in the right triangle

sin20° = = ( multiply both sides by 10 )

10 × sin20° = x , then

x ≈ 3.42 ( to the nearest hundredth )

4.6875 pounds

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
