Mathematics
1 answer:
zmey [24]3 years ago

Answer:

7

Step-by-step explanation:

Because these two triangles share an angle and their corresponding sides are parallel, they are similar.

So, we can set up a proportion relating corresponding sides:

10 / (10 + 8) = (3x - 6) / (3x - 6 + 12)

10/18 = (3x - 6) / (3x + 6)

Cross-multiply:

18 * (3x - 6) = 10 * (3x + 6)

54x - 108 = 30x + 60

24x = 168

x = 168/24 = 7

The answer is 7.

What is the value of x and y?
Pavel [41]

Answer:

x=\boxed{2}

y=\boxed{4}

Step-by-step explanation:

\begin{cases} y= 6x-8... (1)\\\\y=-3x+10...(2)\end{cases}

From equations (1) & (2), we find:

6x - 8 = - 3x +10

\therefore 6x+3x = 8+10

\therefore 9x = 18

\therefore x =\frac{18}{9}

\therefore x = 2

Plug x = 2 in equation (1)

y = 6(2)-8 = 12-8 =4

So,

x=\boxed{2}

y=\boxed{4}

Find the total surface area of the net.​
Elanso [62]

Answer:

87.8 square meters

Step-by-step explanation:

First of all, find the area of the three recthangles.They are all 9m long and 3m wide. 9*3 is 27, and since there are three of them, 27*3 is 81.

To find the area of the two triangles, you could do 3*2.6. Normally, you would halve the values because they are triangles but since there's two of them it cancels out.

3*2.6 is 7.8, and adding that to the area of the rectangles gets the equation 81+7.8 which comes out to 87.8 square meters.
