Does anybody know this?Find the area of the regular polygon
sweet [91]

Answer:

<h2>2,268 square units</h2>

Step-by-step explanation:

Step 1

Find the area of 1 Triangle

To find this, we will use this formula:

A=\frac{1}{2} *B*H

Let's use the formula!

A=\frac{1}{2} *14*27\\=\frac{1}{2}* 378\\=189

<em>The area of 1 triangle is 189 square units</em>

<em></em>

Step 2

Find the area of the whole intire shape by multiplying the area of 1 triangle with the amount of sides.

There are 12 sides, so let's multiply 189 by 12

189x12=2268

<h2>Hence, the area of the regular polygon is 2,268 square units</h2>

Find the measures of two complementary angles, ÐA and ÐB, if mÐA = (7x + 4)° and mÐB = (4x + 9)°. Measure of angle A = ... Measu
Westkost [7]

Answer:

The measure of angle A is 53 degrees

The measure of angle B is 37 degrees

Step-by-step explanation:

Here in this question, we are interested in calculating the measure of the two angle.

When how angles are complementary, it means the sum of both equals 90 degrees

mathematically ;

(7x + 4) + (4x + 9) = 90

7x + 4x + 4 + 9 = 90

11x + 13 = 90

11x = 90-13

11x = 77

x = 77/11 = 7

The measure of angle A = 7x + 4 = 7(7) + 4 = 49 + 4 = 53 degrees

The measure of B = 4x + 9 = 4(7) + 9 = 28 + 9 = 37 degrees
