Show that Sin30° / cos30° = tan30 °

Mathematics
1 answer:
sweet [91]1 year ago
4 0

Answer:

if you multiply both sides by cos 30

LHS = \frac{sin30}{cos30} x cos 30

       = sin 30

RHS = tan 30 x cos 30

       = \frac{sin30}{cos30} x cos 30

       = sin 30

       = LHS

Therefore, sin30° / cos30° = tan30 °

If a polynomial function f(x) has roots 4 – 13i and 5, what must be a factor of f(x)?
Morgarella [4.7K]

The factor of f(x) is (x-(4-13i))

If a polynomial function f(x) has roots 4 – 13i and 5

One of the complex roots is 4-13i

If we have one complex root then there should be one more complex root.

<h3>What is the complex root?</h3>

complex roots come in pairs like (a+ib) and  (a-ib)

so another complex root for 4-13i  is 4+13i

If 'a' is a root then the factor is (x-a)

4+13i is a root

So the factor is (x-(4-13i))

Use the drawing given. (Please answer first blank and let me know it the second blank is correct.)
Lynna [10]

Answer:

EF = 12

arc AG = 62°

Step-by-step explanation:

since ED = 13, EC = 13, so DF = 10/2 = 5

EF² + 13² - 5² = 169 - 25 = 144

EF = √144 = 12

∠AEG = 90° - 28° = 62°

arc AG = 62°
