Given m||n find the value of x

Tan198=asin164=? how to solve this? ?

Which point is an approximate extrapolation for x = 30 from the line of best fit?

Which is the graph of f(x) = 0.5(4)x? the population of a town grows exponentially. after 1 year, the population is 34,560. after 2 years, the population is 37,325. which equation can be used to predict, y, the number of people living in the town after x years? (round population values to the nearest whole number.)
