Answer 1

Answer:

The midpoint of the segment is approximately (3, 2.5).

What is a midpoint of a line segment?

The midpoint of a line segment is given as,

x = (a + c)/2

y = (b + d) / 2

Where (x, y) is the midpoint and (a, b) and (c, d) are the two endpoints.

We have,

To find the midpoint of the segment between two points, we take the average of their x-coordinates and the average of their y-coordinates.

Midpoint = ((x1 + x2)/2, (y1 + y2)/2)

where (x1, y1) = (-1, 2) and (x2, y2) = (7, 3)

Midpoint

= ((-1 + 7)/2, (2 + 3)/2)

= (6/2, 5/2)

= (3, 2.5)

Therefore,

The midpoint of the segment is approximately (3, 2.5).

Answer 2

Answer:

Step-by-step explanation:

First, these are points in a plane, hence should be (-1,2) and (7,3)

Then we'll have

-1+7=6/2=3

2+3=5/2=2.5

Then midpoint is (3,2.5)

Find the slope between (2,10) and (9,1).

Answers

The slope between (2,10) and (9,1) is -9/7.

We have given that,

(x1,y1)=(2,10) and(x2,y2)= (9,1).

What is the formula of the slope?

Slope=rise/run

Sope=y2-y1/x2-x1

use the given values in above formula so we get,

1-10/9-2=-9/7

So, the slope is -9/7.

Solve for y.
50/90-y=5/18

Answers

Answer:

y = 5/18

Step-by-step explanation:

50/90-y=5/18

Lets simplify our fractions

50/90 = 5/9 (divide top and bottom by 10)

5/9 - y = 5/18

Subtract 5/9 from each side

5/9 -5/9 -y = 5/18 - 5/9

-y = 5/18 - 5/9

We need to get a common denominator of 18

-y = 5/18 - 5/9 *2/2

-y = 5/18 -10/18

-y = -5/18

Multiply each side by -1

-1*-y = -5/18 * -1

y = 5/18

Given AABC. m LA= 39°
MLB=104°
AC= 20cm
mLC=
AB =
CB -

Answers

Answer:

∠C = 37° ,

AB = 26.54 cm ,

BC= 33.27 cm

Step-by-step explanation:

Given that in triangle ABC

∠A = 39° AC = 20 cm

∠B = 104°

∵ sum of all the three angles of triangle = 180°

So, ∠C = 180° - ( ∠A + ∠B)

∠C = 180° - (39° + 104°)

∠C = 37°

Now Tan 37° = $(AC)/(AB)$

Or, AB = $(20)/(tan 37°)$

So, AB = 26.54 cm

Again, Sin 37° = $(AC)/(BC)$

So, BC = $(20)/(sin 37°)$

Or, BC = $(20)/(0.601)$

∴ BC= 33.27 cm

Hence ∠C = 37° , AB = 26.54 cm , BC= 33.27 cm Answer
