Answer:

12

Step-by-step explanation:

The sum of the exterior angles of a polygon = 360°

Since there are n sides and each exterior angle = \frac{5n}{2} , then

n × \frac{5n}{2} = 360 ( multiply both sides by 2 to clear the fraction )

5n² = 720 ( divide both sides by 5 )

n² = 144 ( take the square root of both sides )

n = \sqrt{144} = 12

The polygon has 12 sides

2+6i/2-4i = a + bi What is the value of a? What is the value of b?
Talja [164]

\dfrac{2+6i}{2-4i}\\\\\\=\dfrac{2(1+3i)}{2(1-2i)}\\\\\\=\dfrac{1+3i}{1-2i}\\\\\\=\dfrac{(1+3i)(1+2i)}{(1-2i)(1+2i)}\\\\\\=\dfrac{1+2i+3i+6i^2}{1-(2i)^2}\\\\\\=\dfrac{1+5i-6}{1+4}~~~~;[i^2=-1]\\\\\\=\dfrac{5i-5}{5}\\\\\\=\dfrac{5(i-1)}5\\\\=i-1\\\\=-1+i\\\\\text{It is in a form of a +bi so,}~ a = -1~ \text{and}~ b = 1

I neeeed helpssssssssssasss
joja [24]

Answer:

42

Step-by-step explanation:

Hey There!

Angle 3 and Angle 4 are a pair of supplementary angles meaning that added together they will equal 180

So if angle 4 is given to find angle 3 all we have to do is subtract the angle that is given from 180

180-138=42

Therefore angle 3 = 42

You roll a fair 6-sided die what is p (not 3)
Ulleksa [173]
As a fraction, the exact answer is 5/6
In decimal form, the approximate answer is 0.8333

To get this answer, note how there are 5 ways to roll something that isn't a three (1,2,4,5,6) out of 6 ways total (1,2,3,4,5,6)

So you simply divide the two values to get 5/6 = 0.8333

Judy spent 1 hr 15 min less than Sandy exercising last week. Sandy spent 50 minutes less than Mary, who spent 3 hours at the gym
kondaur [170]

Answer:

Judy spent 55 minutes exercising

Step-by-step explanation:

Here, we want to know the amount of time Judy spent exercising.

We proceed as follows;

Mary spent 3 hours , sandy spent 50 minutes less than Mary. The amount of time spent by Sandy is thus 2hrs 10 minutes

Judy spent 1hr 15 min less, the amount of time he spent is thus

2hrs 10 minutes - 1 hr 15 min

2 hrs 10 minutes is same as 2(60) + 10 = 120 + 10 = 130 minutes

I hr 15 minutes = 60 + 15 = 75 minutes

The amount of time spent is thus 130 - 75 = 55 minutes
