Find the value of x

The 2 angles total 120

The 2x angle is 120 - 70 = 50 degrees.

2x = 50

Divide both sides by 2:

x - 25

25° is the right answer.

which you can round up to 7 days, or about a week.the -intercept occurs at a point where , making the value of the intercept. we have , which corresponds to the radius of the algae sample at the start of the experiment.the average rate of change over the given timeframe issince represents the sample's radius, we find that 0.114 is the average rate at which the sample grows in the span of 5 days.
