URGENT!!!!!!!! PLEASE HELP ASAP TIMED!!!!!!!!!!!!!!! HELP!!!!!!!!!!!!!!!!!
rodikova [14]

Answer:

x = 18 and y = 6√10

Step-by-step explanation:

First using pythagoras theorem on the small triangle

h² = 6² + 2²

h² = 36 + 4

h² = 40

h= √40

h = √4 * 10

h = 2√10

Using the similarity theorem;

y/2√10 = 6/2

y/√10 = 6

y = 6√10

To get x we will use the pythagoras theorem

y² = x²+6²

(6√10)² = x² + 36

360 = x² + 36

x² = 360 - 36

x² = 324

x = 18

Hence x = 18 and y = 6√10

What is the value of x in 15x-10= 20
Brut [27]
15x-10=20
+10 +10
15x=30
\15 /15
x=2

you add 10 to both -10 (they cancek eachother out) and 20 (equals 30)
Then you divide 30 by 15 (equals 2) and 15 by 15 (they cancel eachother out)
Then you get x=2
