Step-by-step explanation:
-30i + 52 - 30i
= 52 - 60i.
Here a is 52 and b is -60.
The anwer for that would be a; angle 1 would be congurent to angle 4.
A. The area must be 1/2 x^2, so x must be 7.3. (7.3^2=53.29), 53.29/2=26.645.
It’s b. Because the number with out the x is the y-interact which is -2 then to find the other number I look at the graph and find another point and then count the rise/run which is rising 2 running 3 and it’s also positive that’s why it’s b.
i hope this helps you......
