Please help!! Geometry!! Will mark brainiliest
MrRa [10]

2.   Using the external angle of a triangle theorem.

6x - 17 = 3x - 11 + 2x + 11

6x - 5x = 17

x  = 17

So  m angle K =  2(17) + 11

= 45 degrees   answer

3.  The diagonals are both medians of the triangle so the 2 parts are in the ratio  2:1  so  3:x = 2:1   and   x = 1.5  answer

2:1

The equation 10x + 5y = 150​
Verdich [7]

Answer:

x = 14.5      y = 1

Step-by-step explanation:

get the x alone by subtracting 5y from both sides

10x + 5y = 150

      - 5y    -5y

10x = -5y + 150

divide both sides by 10

<u>10x</u> = <u>-5y + 150</u>

10            10

x = -0.5y + 15

Now that we've solved for x, we can plug it into the original equation

10 (-0.5y + 15) + 5y = 150

now we solve for y the same way we did x

first distribute 10 into (-0.5y + 15)

-5 + 150 +5y = 150

now we get the y alone

-5 + 150 + 5y = 150

+5  -150            -150 +5

5y = 5

now divide by 5

<u>5y</u> = <u>5</u>

5     5

y = 1

now that we have both x and y, we plug y into our solution for x

x = -0.5y + 15

x = -0.5(1) + 15

x= -0.5 + 15

x = 14.5
