Write a number in which the digit 3 is ten times the value of the digit 3 in 9.431

IgorC [24]

Answer:

Step-by-step explanation:

One number would be

9.31

The 3 in this number is 3/10

The 3 in the given number is 3/100

3/10 is 10 times bigger than 3/100

3/10 = 0.3

3/100 = 0.03

0.03 * x = 0.3 Divide both sides by 0.03

0.03/0.03 x = 0.3/0.03

x = 10

PLEASE HELP ASAP <br> TRIGONOMETRY

otez555 [7]

Answer:

11). x = 25.8°

12). x = 67.3°

Step-by-step explanation:

11). By using sine rule in the given triangle,

cos(x) = $\frac{\text{Adjacent side}}{\text{Hypotenuse}}$

cos(x) = $\frac{27}{30}$

x = $\text{cos}^{-1}(\frac{9}{10} )$

x = 25.84

x ≈ 25.8°

12). By applying tangent rule in the given triangle,

tan(x) = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

tan(x) = $\frac{43}{18}$

x = $\text{tan}^{-1}(\frac{43}{18} )$

x = 67.29°

x ≈ 67.3°
