Suppose you are given two angles A and B in which angle a is equal to angle b. If the measure of a compliment of angle a is equa

zepelin [54]

5x + 20 = 90 - a = 90 - (3x + 40)
5x + 20 = 90 - 3x - 40 = 50 - 3x
5x + 3x = 50 - 20
8x = 30
x = 30/8 = 15/4

b = 3(15/4) + 40 = 45/4 + 40 = 51.25
The measure of a supplementary angle is 180 - 51.25 = 128.75

Suppose numbers are x and y

Product of x and y is -2

$xy=-2$

And sum of x and y is -1

$x+y=-1$

Answer:

Question 1 : The answer is 143.3 miles

Question 2 : The answer is 120 minutes

Step-by-step explanation:

1.Based on the give conditions:

$43 \times 90 \div 27 \\ calculate \frac{43 \times 90}{27} = \frac{430}{3}$ $= 143.3$

2. 90 miles = 75min

143.3 ÷ 90 = 1.6

75 × 1.6 = 120

so the answer is 120 min

Which of the following arguments correctly justifies the second step of the flow proof of the triangle angle sum theorem below

pochemuha

We need to see the second step of the proof, so we know what needs to be justified. It would also be nice to see the list of answer choices. I'll never understand how someone who can't answer the question and has to ask someone else can then go ahead and decide that the person helping him only needs to see parts of the question.
