Answer:
The answer to your question is below
Step-by-step explanation:
9)
They are supplementary angle. The sum of supplementary angles is 180°.
b + 50 = 180
-Solve for b
b = 180 - 50
b = 130°
10)
They are vertical angles. Vertical angles measure the same
b = 43°
11)
They are vertical angles. Vertical angles measure the same.
b = 73°
12)
They are supplementary angles. The sum of supplementary angles is 180°
b + 35 = 180
-Solve for b
b = 180 - 35
b = 145°
Answer:
i think that the answer is 5°
The domain would have to be greater than or equal to 0, assuming x is the number of people attending. You can't have a negative number of people!
Check the picture below.
so the quadrilateral is really just a parallelogram below a triangle, so let's simply get the area of each and sum them up.
12 × 12 =144+ 6 = 150 I'm pretty sure
