74

Step-by-step explanation:

Both angles x and 106 are supplementary which means

x+106=180

x=180-106

x=74

74°

Step-by-step explanation:

In the image you have provided, angle 'x' and 106° are co-interior angles. This mean that both the angles add up to 180°. We can easily identify co-interior angles because the angles would be inside. The other types of angles you can get is vertical and corresponding. Using the information in the second sentence we can set up an equation,

⇒ Form an equation

→ x + 106 = 180

⇒ Minus 106 from both sides to isolate x

→ x = 74°

The values of angle x is 74°

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001
