M∠A+ m∠B = ? How do you know this?

Mathematics
1 answer:
pychu [463]3 years ago
4 0

Answer:

Step-by-step explanation:

If m∠A + m∠B = m∠B + m∠C, subtract  m∠B from both sides  [ subtraction property of equality ].

We get that m∠A  = m∠C     and by the  symmetric property of equality,  m∠C = m∠A

During a winter's night, the low temperature was recorded at 19oF. The wind-chill temperature that night was -7^oF. What was the
erastovalidia [21]

Answer:

-26oF

Step-by-step explanation:

The difference between the low temperature and the wind-chill temperature is the result obtained when the low temperature is subtracted from the wind-chill temperature.

This difference

= -7oF - 19oF

= -26oF

The negative sign shows that there was a fall in temperature.

16 + 4x + 2x-3x + x = 0
NemiM [27]
16 + 4x + 2x - 3x + x = 0

First, simplify 16 + 4x + 2x - 3x + x to get 16 + 4x. / Your problem should look like: 16 + 4x = 0
Second, subtract 16 from both sides. / Your problem should look like: 4x = -16
Third, divide both sides by 4. / Your problem should look like: x = -\frac{16}{4}
Fourth, simplify \frac{16}{4} to get 4. / Your problem should look like: x = -4

Answer: x = -4

calculate the distance between the two points shown on the graph below give your answer correct to 2 decimal places if necessary
GenaCL600 [577]

Answer:

Find the distance between (-1, 1) and (3, 4).

This problem is solved simply by plugging our x- and y-values into the distance formula:

D=(3−(−1))2+(4−1)2−−−−−−−−−−−−−−−−−−√=

=16+9−−−−−√=25−−√=5

Sometimes you need to find the point that is exactly between two other points. This middle point is called the "midpoint". By definition, a midpoint of a line segment is the point on that line segment that divides the segment in two congruent segments.

If the end points of a line segment is (x1, y1) and (x2, y2) then the midpoint of the line segment has the coordinates:

(x1+x22,y1+y22)

Find the distance between the points (8,10) and (4,7)
r-ruslan [8.4K]

Answer: 7 is the distance in between the points

Step-by-step explanation: How you find the distance between points is pretty simple once you know how to do it!

So first take your X coordinate take the first one (8) and subtract it from the second one (4) 8-4=4 so now we have 4 put that aside for a moment,

Now take your Y coordinate subtract the first one (10) from the second one (7), 10-7=3

Finally add the 3 and 4 together you get 7 that is why 7 is the distance in between the points

If you need further help or instruction please let me know!

PLZZZZ HELPPPPPP EXTREME FROWNIES IF U DONT ITS MATTTTHHHH
STALIN [3.7K]

Answer:

x=9 and angle B=40

Step-by-step explanation:

5x-5=3x+13

Subtract -3 on both sides of x

5x(-3)-5=3x(-3)=+13

2x-5=13

Add 5 to both sides

2x-5(+5)=13(+5)

2x=18

Divide by 2

x=9

Now that you know x=9, plug it into 3x+13

So, 3(9)+13= 27+13= 40

so ya thats my answer hopefully it helps

(btw both angle A and B are the same so thats why u put them equal)
