Answer: The answer is (C) 180°.
Step-by-step explanation: Given that m∠A = 40°. ∠B is a complement of ∠A and ∠C is a supplement of ∠B. We are to find m∠B + m∠C.
Since ∠B is a complement of ∠A, so we have
Now, since ∠C is a supplement of ∠B, so we have
Therefore,
Thus, (C) is the correct answer.
Answer:
Find the function of two points first. Then check whether the third point is on it
Answer:
Step-by-step explanation:
y - y1 = m(x - x1) y1 = 1 x1 = 2 m = -1/3
y - 1 = -1/3(x - 2)
y = -x/3 + 2/3
Answer:
A≅407.34 au (area units)
Step-by-step explanation:
we must find the area generated by equations a., b., and c. To do this we must graph and the areas and determine their points to evaluate
As seen in the graphs (1, 2) we have the area generated by equations a. b. and the limits within which the area should be evaluated are those determined by c.
Finally we find A (view graph 3)
