SOLVE FOR X PLEASEEE HELP​

2.2857

Step-by-step explanation:

To solve this I'm going to find Angle A

I have the adjacent and opposite side so using TOA is easiest

let a= angle

tan(a)=4/7

a=29.74488

Now that we have the angle A we can only look at triangle ABC

To solve for x we use TOA again

tan(29.74488)=x/4

4tan(29.74488)=x

x=2.2857

2.28

Step-by-step explanation:

∆ABC~∆ADE

So, x/4=4/7

7x=16

x=16/7

x=2.28

the answer is 0.3175 hope that you ^w^

also you might actually want to put this picture up if you want people to solve it luckily i remember this question

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.
