Plz and try to find U ​

u=6m

Step-by-step explanation:

The 2 triangles, LKO and NMO are similar by AAA congruence. Therefore, we can use ratios to find u.

Notice how the 5 and 10 are each inbetween the double and single angle congruence indicators in the image. u and 3 are also both in between the right angle and double line indicator.

When you cross multiply, you get 5u=30, and after simplifying you get u=6 m

Another way you could have done this is by finding the scale factor.

The scale factor between corresponding sides in the 2 triangles is 2. (5 x 2 = 10).

When you multiply 3 by 2, you also get 6 m.

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
