We have been given that area of triangle ABC is 3√2 square inches.

We know that area of triangle an be found using trigonometry as:







Now, we will use inverse sine to find the value of angle A as:



Therefore, the measure of angle A is approximately 28 degrees.
You have to multiply to find it
The equation in y = mx+b form is y = -450x+2745
where,
x = number of hours that have passed by
y = distance to destination in miles
The y intercept is 2745 since this is the initial starting y value, aka the starting distance. Therefore b = 2745.
The slope is -450 or -450/1 since for each hour, the distance goes down by 450. You can think of it as
slope = (change in y)/(change in x)
slope = (change in distance)/(change in time)
slope = (-450 miles)/(1 hour)
slope = -450
