Answer:

D. 7

Step-by-step explanation:

Since the two triangles are similar the ratio will be

56 : x

48 : 6

We can simplify 48 : 6 as 8 : 1 by dividing both 48 and 6 by the factor 6. Then you can compare 8 : 1 and 56 : x. When you do this you'll see that to go from 8 to 56 you have to multiply by 7. So you have to do that for 1 as well. 1 x 7 = 7. Therefore x = 7.

What is the mean of the following data values 22,37,49,15,72

nexus9112 [7]

Mean simply means average
so just add them all up and divide by 5

22 + 37 + 49 + 15 + 71 = 195
195/5 = 39

mean = 39

RS=2x-8, ST = 11, RT = x+10

ziro4ka [17]

Answer:

$Equation~=~\Large\boxed{2x+3=x+10}$

$x~=~\Large\boxed{7}$

$RS~=~\Large\boxed{6}$

$RT~=~\Large\boxed{17}$

Step-by-step explanation:

<u>Given information</u>

$RS=2x-8$

$ST=11$

$RT=x+10$

<u>Derived expression from the given information</u>

<em>Presumably, I think this is a combination of segments</em>

$RS+ST=RT$

<u>Substitute values into the given expression</u>

$(2x-8)+(11)=(x+10)$

<u>Combine like terms</u>

<em>The following is the expression</em>

$\Large\boxed{2x+3=x+10}$

<u>Subtract 3 on both sides</u>

$2x+3-3=x+10-3$

$2x=x+7$

<u>Subtract x on both sides</u>

$2x-x=x+7-x$

$\Large\boxed{x=7}$

<u>Substitute the x value into corresponding expressions to determine the final value</u>

$RS=2x-8=2(7)-8=14-8=\Large\boxed{6}$

$RT=x+10=(7)+10=\Large\boxed{17}$

Hope this helps!! :)

Oksi-84 [34.3K]

Answer:

QBO=12 degrees

Step-by-step explanation:

angle QAO=angle OAS so:

2x+6=4x-12

reducing:

2x=18

x=9

substituting x into QBO=3x-15 then:

angle QBO=3(9)-15=12 degrees
