Use the rules of significant figures to simplify the following expression:<br> 47.58 - 6.4

irina1246 [14]

41.18 because it’d you subtract 58 from 4 you get 18 and that behind the decimal so it’s 0.18 and 48-6 which is 41 so 47.58 - 6.4 equal to 41.18

How many degrees is the angle measurement of x?

jenyasd209 [6]

Answer:

x ≈ 37.13°

Step-by-step explanation:

using the sine ratio in the right triangle

sin x = $\frac{opposite}{hypotenuse}$ = $\frac{13.4}{22.2}$ , then

x = $sin^{-1}$ ( $\frac{13.4}{22.2}$ ) ≈ 37.13° ( to the nearest hundredth )
