What’s the measure of angle F?

Naily [24]

Answer:

F = 105

Step-by-step explanation:

The sum of the interior angles of a polygon with n sides is (n – 2)180.

This polygon has 6 sides so the sum of the interior angles is (6-2) * 180 =

720

Add up the angles

x-60 +x-40 +130 +120 +110 + x-20 +x-20 = 720

Combine like terms

4x +220 = 720

Subtract 220 from each side

4x+220-220 = 720-220

x = 500

Divide each side by 4

4x/4=500/4

x = 125

We want to find angle F

F = x-20

= 125-20

If StartFraction pi Over 2 EndFraction less than t less than pi , which of the following is true?

oksian1 [2.3K]

Answer:

b. cosine t less than 0 and cotangent t greater than 0

Step-by-step explanation:

We have the following relation

$\frac{\pi }{2} < t$

if we apply the cosine function in the relation we get:

$cos\frac{\pi }{2}$

$-1$

the cosine of t is between 0 and -1 then (cosine t less than 0)

If we now apply cotangent function in the relation:

$cotan\frac{\pi }{2}$

$0$

This means that cotang is greater than 0, therefore the correct answer is b. cosine t less than 0 and cotangent t greater than 0

A monument outside city hall has dimensions as shown below in the figure. If one gallon of paint can cover 213 ft^2, how many ga

rusak2 [61]

Answer:

sides

14 X 22 = 308 square foot there are four of these

308 X 4 = 1232 square foot.

triangles

A= 0.5 X b X h

0.5 X 14 X 10 = 70 square foot again there are four of these 70 X 4 = 280 square foot

1232 + 280 = 1512 square foot

1512/213 = 7.09859154

8 gallons of paint will need to be purchased.

In a ten pin bowling the highest possible score in a single game is 300. At one point in the season, John had an average score o

Sindrei [870]

Answer:

John need to get 293 in his next game to bring his average up to 183.

Step-by-step explanation:

John starts with N games played and averaging 177 points per game.

In game N+1, John scored 199 points.

$\frac{177N + 199}{N+1}=178\\177N+199=178N+178\\N=21\\$

So, John has now played (N+1) = 22 games.

We need to know what score John needs in game 23 to bring his average to 183.

$\frac{177*21 + 199+Y}{23}=183\\3916+Y=4209\\Y=293\\$
