Question

Plz and try to find U ​

Answer 1

Answer: u=6m

Explanation:

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

`(5)/(10)=(3)/(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.

Answer 2

u = 6

Explanation:

We can use a ratio to solve

3 5

----- = ---------

u 10

Using cross products

3*10 = 5u

30 = 5u

Divide by 5

30/5 = 5u/5

6 = u
