The set A U B is represented by shading both circles A and B (also the overlapping region as well). Any point in set A U B will be in either A, B or both.
D.
-5(-1) + 2(2) = 5 + 4 = 9
-3 + 10 = 7
Is this what you are looking for? I hope this helps!
Answer:
Step-by-step explanation:
We need the chart or other information.
The measure of angle theta is 30 degrees.
This is a 30-60-90 triangle where the short leg is half that of the hypotenuse. The short leg is opposite the smallest angle 30 degrees.
You can use trig to find that
sin(angle) = opposite/hypotenuse
sin(theta) = 5/10
sin(theta) = 0.5
theta = arcsin(0.5)
theta = 30 degrees
