In ΔRST, m < R = 104°, r = 20, and t = 10. Find the m < S, to nearest degree.

Answer:

47°

Step-by-step explanation:

The law of sines helps you find angle T. From there, you can find angle S.

sin(T)/t = sin(R)/r

sin(T) = (t/r)sin(R) = (10/20)sin(104°)

T = arcsin(sin(104°)/2) ≈ 29°

Then angle S is ...

S = 180° -R -T = 180° -104° -29°

∠S = 47°

Triangle has 180 degrees:
180=2m-3+m+4+3m+5
Combine like terms
180 = 6m+6
Subtract 6 from 180
174=6m
Divide by 6
m=29

Brainliest if that helped, please :)

Use the definition of a derivative to find f’(x).

tatyana61 [14]

Answer:

f'(x) = $-\frac{9}{x^2}$

Step-by-step explanation:

i) f(x) = 9 / x

ii) f'(x) = $$\lim_{h\to 0} \frac{f(x+h) - f(x)}{h} $ \hspace{0.2cm}$

$= $\lim_{h\to 0} \frac{\frac{9}{x+h} - \frac{9}{x} }{h} = \hspace{0.1cm} $\lim_{h\to 0} \frac{9x - 9(x+h)}{hx(x+h)} $ \hspace{0.1cm} = \hspace{0.1cm}$\lim_{h\to 0} \frac{-9h}{hx(x+h)} = $\lim_{h\to 0} \frac{-h}{x(x+h)} = \frac{-9}{x^2}$$
