Answer: (-7,-1)

Complete question is attached below

The coordinates of J is (-15,-5) and K is (25,15)

The formula to find point E (x,y) is

x=\frac{m}{m+n}(x_2-x_1)+x_1

y=\frac{m}{m+n}(y_2-y_1)+y_1

We know the ratio is 1:4

m=1  and n=4

(x1,y1) is (-15,-5) and (x2,y2) is (25,15)

Now plug in all the values in the formula and find out x and y

x=\frac{1}{1+4}(25-(-15))-15=\frac{1}{5}*40 - 15 = -7

y=\frac{1}{1+4}(15-(-5))-5=\frac{1}{5}*20 -5=-1

The point E is (-7,-1)

A right triangle has leg lengths 8 and x. The hypotenuse length is (x + 2). What is the length of the hypotenuse?
umka2103 [35]

Answer:

17 is the length of the hypotenuse.

Step-by-step explanation:

The pythagora theorem tells us a²+b²=c², where C is hypotenuse.

Replace the given info into the formula:

8² + x² = (x+2)²

64 + x² = x² + 4x + 4

64 - 4 = 4x

60 = 4x

x = 60/4

x = 15

Hypotenuse length is 15+2=17

Can anyone help with this?
Morgarella [4.7K]

Answer:

111 degrees

Step-by-step explanation:

the total degrees in a hexagon is 720 degrees.

the known angles add up to 379, so there is 341 degrees left.

angle KFE is 105 degrees because it adds up to 180 degrees with GFK.

angle LAD is 130 degrees because it adds up to 180 degrees with BAD.

130+105=230, so there is now 111 degrees left and that is angle x

If the perimeter of a four sided figure is 124m, determine the maximum area that can be obtained
MAXImum [283]
Just do a square and do 124/4= 31 and then to get the area you do length multiplied by length which is 31 X 31 which equals 961m squared.
