∠A=6x+12

Mathematics
1 answer:
topjm [15]3 years ago
3 0

Answer:

x = 17

∠A = 114°

Step-by-step explanation:

In the figure attached, the complete question is shown.

From the figure, we know that:

∠A = ∠B

Replacing with the expressions, we get:

6x+12 = 3x+63

6x - 3x = 63 - 12

3x = 51

x = 51/3

x = 17

∠A = 6(17)+12

∠A = 114°

A 20-sided regular polygon has an angle measure represented as 3gº.
Andre45 [30]

The value of g in the 20 sided regular polygon is 54.

<h3>How to find the angles of a regular polygon?</h3>

If all the polygon sides and interior angles are equal, then they are known as regular polygons.

The polygon given is a 20 sided regular polygon and the measure of each angle is 3g degrees.

Therefore, let's find g.

The sum of interior angles of a 20 sided polygon is as follows:

180(n - 2) = 180(20 - 2) = 180(18) = 3240

Therefore,

each angle = 3240 / 20 = 162

Hence,

162 = 3g

g = 162 / 3

Therefore,

g = 54
