Answer:

A. 60°

Step-by-step explanation:

There's a very straight-forward explanation for this, thank god! XD

For this type of problem, there's a rule to follow for the outside angle. X and 120 should equal 180, so all you need to do is fill that gap.

180-120 = 60

60 is your answer because it completes the whole angle.

Find the area of a regular pentagon with the apothem of 24.3 cm and a side length of 35.3

steposvetlana [31]

Answer: $A=2144\ cm^2$

Step-by-step explanation:

For this exercise you need to use the following formula for calculate the area of regular polygon:

$A=\frac{s^2n}{4tan(\frac{180}{n})}$

Where is "s" the length of any side, "n" is the number of sides.

Int this case you know that it is regular pentagon, which means that it has five sides. Then you can identify that the values of "n" and "s":

$s=35.3cm\\n=5$

Therefore, substituitng values into the formula, you get that the area f the pentagon is:

$A=\frac{(35.3cm)^2(5)}{4tan(\frac{180}{5})}\\\\A=2144\ cm^2$

The measure of angle 3 is 42°. <br><br> What is the measure of angle 1 in degrees?

Svetradugi [14.3K]

Answer:

Angle 1 is 48°

Step-by-step explanation:

So angle 1 + angle 2 + angle 3 = 180°

Angle 2 = 90°

Angle 3 = 42°

180 - 90 - 42 = 48°
