GDH=180 because it is a supp. So 62+(x+2)=180
Subtract 62 from both sides

Den subtract 2
Which is 116
Hope this helps good luck

What is the value of n to the nearest whole number?

shtirl [24]

The value of n to the nearest whole number is 22

<h3>Trigonometry</h3>

From the question, we are to determine the value of n to the nearest whole number

In the diagram,

The given triangle is a right triangle.

Thus,

Using the <em>Pythagorean theorem</em>, we have that

n² = h² + k²

∴ n² = 9² + 20²

n² = 81 + 400

n² = 481

n = √481

n = 21.93

n ≈ 22

Hence, the value of n to the nearest whole number is 22

pshichka [43]

Answer:

The correct option is B. The length of OB' is 3 units.

Step-by-step explanation:

The rule of dilation is D₀,₄. It means dilation by scale factor 4 with center of dilation is origin.

$\text{Scale factor}=\frac{\text{Distance between center and any point of the image}}{\text{Distance between center and corresponding point of the Preimage}}$

$\text{Scale factor}=\frac{OB'}{OB}$

$4=\frac{OB'}{\frac{3}{4}}$

$4\times \frac{3}{4}=OB'$

$3=OB'$

The length of OB' is 3 units. Therefore the correct option is option is B.
