An angle measures 79.4 degrees more than the measure of its supplementary angle. What is the measure of each angle?

Answers

Answer:

The angles are: 50.3 and 129.7

Step-by-step explanation:

The sum of supplementary angles is 180°.

Let x be one angle then the other angle will be x+79.4

Using the supplementary angle sum

[tex]x+x+79.4 = 180\\2x+79.4 = 180\\2x = 180-79.4\\2x = 100.6\\\frac{2x}{2} = \frac{100.6}{2}\\x = 50.3[/tex]

For the measurement of 2nd angle

x+79.4 => 50.3+79.4 => 129.7

Hence,

The angles are: 50.3 and 129.7

log_6⁡(x+1)+log_6⁡x=1

Answers

This is pretty simple once you figure out the trick.

All you have to do is make the args common.

Meaning [tex]log_{6}(x + 1) + log_{6}(x) = 1[/tex] is nothing but [tex]log_{6}(x(x + 1)) = 1[/tex]

Which is nothing but: [tex]log_{6}(x^2 + x) = 1[/tex].

Now using the scorpion tail method, this equation can be reframed to being: [tex]6 = x^2 + x[/tex]. You bring 6 to the other side and it'll become: [tex]x^2 + x - 6 = 0[/tex]

Factorise it and you get: [tex](x - 2) * (x + 3)[/tex]

Henceforth, the solution would be [tex]2[/tex] and [tex]-3[/tex]. :D

Answer:

81 / 40

Step-by-step explanation:

The Maclaurin expansion of sin x is:

sin x = ∑ₙ₌₀°° (-1)ⁿ x²ⁿ⁺¹ / (2n+1)!

sin x = x − x³/3! + x⁵/5! − x⁷/7! + ...

Substituting this into the limit:

lim(x→0) [sin(3x) − 3x + ⁹/₂ x³] / x⁵

lim(x→0) [(3x − (3x)³/3! + (3x)⁵/5! − (3x)⁷/7! + ...) − 3x + ⁹/₂ x³] / x⁵

lim(x→0) [(3x − ⁹/₂ x³ + 3⁵x⁵/5! − 3⁷x⁷/7! + ...) − 3x + ⁹/₂ x³] / x⁵

lim(x→0) (3⁵x⁵/5! − 3⁷x⁷/7! + ...) / x⁵

lim(x→0) (3⁵/5! − 3⁷x²/7! + ...)

3⁵/5!
