3 An open cone has a vertical angle measuring 40°
belka [17]

Answer:

13.41 cm

Step-by-step explanation:

The radius, height, and HALF of vertical angle makes a triangle.

Where

Radius will be the base of the triangle

Height will be the "height" of the triangle

Top angle will be HALF of vertical angle (40/2 = 20)

From the 20 degree angle, the side "opposite" would be the radius, which is 30. The side "adjacent" would be the height, let it be h.

<em>Which trig ratio relates opposite and adjacent? Yes, that is TAN. Thus we can write:</em>

Tan(20) = opposite/adjacent

Tan(20) = 30/h

h = 30/Tan(20)

h = 13.41

So

The height of the cone would be around 13.41 cm

Please help will give 20 points to right answers (will give brainliest to very first correct answer) Tom walks 3.2 km every morn
nignag [31]
For this case we have the following conversions:
 1 mile = 1,609 km&#10;&#10;1 mile = 5,280 feet
 We must apply the conversions to move from kilometers to feet.
 We have then:
 (3.2) * (1 / 1,609) * (5280) = 10500.93226&#10;
 Rounding off we have:
 10501 feet
 Answer:
 
there are 10501 feet in 3.2 km
