Answer:

$\displaystyle m\angle JKM = 50$

Step-by-step explanation:

remember that,

if a side of a triangle expanded exterior so formed is equal to the sum of the two interior angles

so,

$\displaystyle m\angle JKM = 25 + 25$

simplify addition:

$\displaystyle m\angle JKM = 50$

How do i solve this 3x + y = 36 5x + y = 56

iren2701 [21]

Answer:

x=10, y=6

Step-by-step explanation:

the send equation minus the first.

(5x+y)-(3x+y)=56-36

2x=20--->x=10

then put x=10 to the first equation, 3*10+y=36, get y=6

The endpoints of CD are C(3,−5) and D(7, 9). The coordinates of the midpoint M of CD are?

Nutka1998 [239]

Answer:

M(5,2)

Step-by-step explanation:

We use the midpoint rule:

$( \frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2} )$

We just have to find the arithmetic mean of the x and y-coordinates.

The endpoints of CD are given as C(3,−5) and D(7, 9).

We substitute these values to get:

$( \frac{7 + 3}{2}, \frac{9 + - 5}{2} )$

$( \frac{10}{2}, \frac{4}{2} )$

$(5, 2)$

Therefore the coordinates of the midpoint M of CD are (5,2)
