Which is greater: An angle showing a turn through 1/6 of a circle or an angle showing to turn through 1/5 of a circle explain yo
Rashid [163]

Answer:

An angle showing a turn through 1/5 of a circle is greater

Step-by-step explanation:

we know that

A complete circle represent 360\°

so

An angle showing a turn through 1/6 of a circle is

(360\°)*(\frac{1}{6})=60\°

An angle showing a turn through 1/5 of a circle is

(360\°)*(\frac{1}{5})=72\°

therefore

An angle showing a turn through 1/5 of a circle is greater

In the following diagram, BC is parallel to DE.
PilotLPTM [1.2K]

Answer:

Your answer would be 37°

Step-by-step explanation:

Since BC and DE are parallel, certain angles will be the same, such as the missing interior angle of the triangle and ∠DAF, which will also have the same measure as x.

We know that the sum of all of the interior angles of a triangle must equal 180°. So, we add 41 and 102 to get 143. This means that the missing interior angle must be 37°, since 37+143=180.

As mentioned above, because BC and DE are parallel, the missing interior angle has the same measure as ∠DAF, which is a vertical angle to x, and therefore also has the same measure. So, the measure of x is 37°.

Hope this helps you!
