No, the inscribed angle is simply half the central angle

What are the values of p and q?

andrew-mc [135]

Answer:

If we multiply two numbers together, we get a product. A product is the same as a multiple.

If we divide two numbers, we get a factor of the number we are dividing. A factor is the same as a divisor.

Knowing this, we can create two equations.

pq = 210 eq1

p/q = 14 eq2

We have a system of equations. If we substitute eq2 into eq1 so the eq1 is in terms of eq1, we obtain

(14q)q = 210

14q2 = 210

Solve for q from this equation.

q2 = 15

Square-root both sides of the equation.

q = √15

8. For questions 8-9, determine whether the two figures are similar. If so, give the scale factor of the smaller figure to the l

Vinvika [58]

Question 8:

Your choice is correct: two figures are similar if all correspondant sides are in the same ratio.

In your case, the figure on the right have correspondant sides which are all three times the figure on the left, since

$12 = 4\times 3, 21 = 7\times 3, 54 = 18\times 3$

So, the two figures are similar and their ratio is 1:3.

Question 9:

We follow exactly the same approach: let's see if the radii and the heights are in the same ratio: the radii are in ratio

$\cfrac{3.2}{2} = 1.6 = \cfrac{16}{10} = \cfrac{8}{5}$

While the heights are in ratio

$\cfrac{6.4}{4} = 1.6 = \cfrac{16}{10} = \cfrac{8}{5}$

So, the answer is again yes, they are similar, and the ratio is 1.6.
