So we know that around the center is equal to 360. So (15 + 5x) = (4x + 20) to find what x equals you subtract 4x from each side to get 15 + x = 20 now subtract 15 from both sides to get x = 5. Now we know that x = 5 so the 2 angles are 40 degrees each. Now subtract those two angles from 360 and you get 280. Then divide by two and you get 140. So, now we know those two angles are equal to 140.

Good luck with your school work. Sorry it took so long.

when price of indomie noodles was lowered from #50 to #40 per unit, quantity demanded increases from 400 to 600 units per week.

Nataly [62]

Answer:

The price elasticity of demand is -10

Step-by-step explanation:

Given

$p_1,p_2 = 50,40$

$q_1,q_2 = 400,500$

Solving (a): The coefficient of price elasticity of demand (k)

This is calculated as:

$k = \frac{\triangle q}{\triangle p}$

So, we have:

$k = \frac{500 - 400}{40 - 50}$

$k = \frac{100}{-10}$

$k = -10$

<em>Because |k| > 0, then we can conclude that the company made a wise decision.</em>

A local middle school adopted a policy for school uniforms. Students can wear black pants or tan pants. They can wear a yellow s

ValentinkaMS [17]

The answer is 8 because you have black and tan pants so 2 pairs and then a green, red, white, and yellow shirt sooooo you have 4 choices of shirts to pair with your pants. So 2•4=8

Which function is equivalent to the inverse of y=sec(x)

kipiarov [429]

From the identity:

$sec(x)= \frac{1}{cos(x)}$

$f(x)=sec(x)= \frac{1}{cos(x)}$

the inverse of f is g such that f(g(x))=x,

we must find g(x), such that $\frac{1}{cos[g(x)]}=x$

thus, $cos[g(x)]= \frac{1}{x}$

$g(x)=cos^{-1} (\frac{1}{x})$

Answer: b. g(x)=cos^-1(1/x)
