Answer:

x = 9

Step-by-step explanation:

A line segment parallel to a side of a triangle and intersecting the other 2 sides divides the 2 sides in proportion, that is

$\frac{9}{72}$ = $\frac{1}{8}$ = $\frac{3x-20}{56}$ ( cross- multiply )

8(3x - 20) = 56

24x - 160 = 56 ( add 160 to both sides )

24x = 216 ( divide both sides by 24 )

x = 9

Answer:

The value of x = 9

Step-by-step explanation:

From the figure

we can see that, the middle line segment is parallel to one side of the triangle.Therefore we can write,

9/72 = (3x - 20)/56

9*56 = 72(3x -20) [cross multiplying]

56 = 8(3x - 20) [divided by 9]

7 = 3x - 20 [divided by 8]

3x - 20 = 7

3x = 27

x = 27/3 = 9

Therefore the value of x = 9

10. Find the area of the shaded region.

Semenov [28]

Answer:

Area = 114

Step-by-step explanation:

We first must find the area of the larger outside rectangle.

Area = length × width

15 × 8 = 120

Then we find the area of the smaller inside rectangle.

4 × 1.5 = 6

Since the small rectangle is not shaded we have to subtract its area from the larger shaded rectangle's area.

120 - 6 = 114
