The area is 48
I did 12x8/2 using the formula height x base divided by 2
hope it helps
A=45 degree I had the same example ... Even if a angle is 90 degrees is not necessarily a right triangle, so the angle A = 45 degrees
Answer:

Step-by-step explanation:
Derivative indicates rate of change of dependent variable with respect to independent variables. It indicates the slope of a line that is tangent to the curve at the specific point.
Given:
Number of bees is modeled by the function 
The daily high temperature is increasing at a rate of 2 °F per day when the number of bees spotted is 100.
To find:
rate of change of number of bees when 100 bees are spotted
Solution:

Differentiate with respect to t,

Put 

At x = 100, 
The only factor that both terms have is d
