Answer:

use The Law of Cosines first to calculate one of the angles

then use The Law of Cosines again to find another angle

and finally use angles of a triangle add to 180° to find the last angle.

cos(C) = (a2 + b2 − c2)/2ab

cos(A) = (b2 + c2 − a2)/2bc

cos(B) = (c2 + a2 − b2)/2ca

Answer:

Lets say its a right angle : we know that it is 90 degrees

Since  triangles are congruent to each triangle, each triangle has half as many degrees, namely 180. So this is true for any right triangle.

What is the volume of a cylinder, in cubic m, with a height of 5m and a base diameter of 20m? Round to the nearest tenths place
makvit [3.9K]

Answer: Volume of the cylinder = 1570 m³

Step-by-step explanation:

The formula for determining the volume of a cylinder is expressed as

Volume = πr²h

Where

r represents the radius of the cylinder.

h represents the height of the cylinder.

π is a constant whose value is 3.14

From the information given,

Diameter = 20 m

Radius = diameter/2 = 20/2

Radius = 10 m

Height = 5 m

Therefore,

Volume = 3.14 × 10² × 5

Volume = 3.14 × 100 × 5

Volume = 1570 m³ rounded to the nearest tenth

The histogram shows the ages of cars sold at a car auction. what percent of the cars was less than 20 years old or more than 40
Alexus [3.1K]
The histogram is attached. Every column shows on the bottom the range of age and on the left the number of cars of that particular age.

In order to find the percentage of cars with less than 20 years or more than 40 years, you have to sum up the numbers of cars in the first two columns from left (age 0-9 and 10-19) and the last two (age 40-49 and 50-59).
The number of cars of requested age is: 3 + 2 + 0 + 3 = 8

Now, you need to calculate the total number of cars (sum the cars of every column): 3 + 2 + 8 + 4 + 0 + 3 = 20

Lastly, you need to calculate the ration between the cars of requested age and the total number of cars, and transform it into a percentage:
8 ÷ 20 = 0.40 = 40%

Therefore, your answer is 40%.
