The dotted line is parallel to segment BC.  This means that angle ABC is also 18 degrees.
Given that we are looking for the opposite of angle ABC and are give the adjacent of angle ABC (2) we can use the tan function to calculate x
tan 18 = opposite/adjacent
tan 18 = x/2
2 tan 18 = x - multiply both sides by 2
x = 0.6948 - simplify

Tan 18 = x/2

⇒ 0.3249 = x/2

⇒ x = 2 * 0.3249 =

⇒ x = 0.6498 ≈ 0.65

Hope it helps!

What is thevmedian of starter repair cost if starters for four different vehicles 316,443,249 and 210
Leni [432]

Answer: 283

Step-by-step explanation:

To find the median, you have to first arrange the figures in the distribution in ascending order:

210, 249, 316, 443

As this is an even distribution, the Median will be found by adding up the second and third numbers and then dividing by 2:

= (249 + 316) / 2

= 283

The perimeter of the first figure is 34 cm and the area is 64 cm².
The perimeter of the second figure is 38 cm and the area is 60 cm².
The perimeter of the third figure is 30 cm and the area is 36 cm².
The perimeter of the fourth figure is 72 cm and the area is 200 cm².
The perimeter of the fifth figure is 30 cm and the area is 36 cm².

To find the perimeter of each, we add the area of all sides.  For the first figure, the missing sides are 1 cm and 6 cm.  To find the area, we have two rectangles whose dimensions are 6x10 and 1x4.

For the second figure, the missing sides are 4 cm and 3 cm.  To find the area, we have two rectangles whose dimensions are 4x12 and 3x4.

For the third figure, the missing sides are 3 cm, 3 cm and 8 cm.  To find the area, we have two rectangles whose dimensions are 4x3 and 3x8.

For the fourth figure, the missing sides are 10 cm, 10 cm, 6 cm and 6 cm.  To find the area, we have two squares whose dimensions are 10x10.

For the fifth figure, the missing sides are 3 cm and 9 cm.  To find the area, we have two rectangles whose dimensions are 3x6 and 6x3.
