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!

Write the equation of the circle with center (2, -3) and a radius of 4.

harkovskaia [24]

C(h,k) radius(r)
C(2,-3) r=4

(x-h)^2 + (y-k)^2 = r^2
(x-2)^2 + (y--3)^2 = 4^2
(x-2)^2 + (y+3)^2 = 16

therefore, the answer is D

What is the length of HG?

Leviafan [203]

Answer:

$HG = 5$

Step-by-step explanation:

Given

$HE = 8mm$

$EF = 12mm$

$Area = 68mm^2$

Find the length of HG

First, it should be noted that the displayed figure is a trapezium

<em>The area of a trapezium is calculated by multiplying the sum of parallel sides by half its height;</em>

In this case;

$Area = \frac{HG + EF}{2} * HE$

Substitute the values of Area, HE and EF

$68 = \frac{HG + 12}{2} * 8$

$68 = (HG + 12) * 4$

Divide both sides by 4

$\frac{68}{4} = \frac{(HG + 12) * 4}{4}$

$17 = HG + 12$

Subtract 12 from both sides

$17 - 12 = HG + 12 - 12$

$5 = HG$

$HG = 5$

<em>Hence, the length of HG is 5mm</em>
