What is the value of y?<br><br><br><br> Enter your answer in the box.<br><br> y =
Olenka [21]

Answer:

y=40\°

Step-by-step explanation:

we know that

An isosceles triangle has two equal sides and two equal angles

The two equal angles are called the base angles and the third angle is called the vertex angle

In this problem the triangle ABC is an isosceles  triangle

so

AB=AC

5x=40\°

x=8\°

The sum of the internal angles of a triangle is equal to 180\°

so

Find the value of y

(2y+20)\°+2(40\°)=180\°

2y=180\°-20\°-80\°

2y=80\°

y=40\°

Please help I’ll mark brainliest
denpristay [2]

Answer:

166.27 m2

Step-by-step explanation:

area of hexagon = \frac{3*\sqrt{3} }{2}*a^{2} where a = length of 1 side

this hexagon is made of 6 equivalent triangle

consider ABC triangle

let AC length be x

<em>AB = 2 * AC = 2x = a</em>

bc^{2} = ab^{2} - ac^{2} \\(4\sqrt{3})^{2} =(2x)^{2}  - x^{2} \\48=3*x^{2}\\ 16=x^{2} \\x=4

Hence a = 8

<u>hence area of hexagon = </u>\frac{3*\sqrt{3} }{2}<u>*</u>a^{2}<u> =  </u>\frac{3*\sqrt{3} }{2}<u> * </u>8^{2}<u> = 166.27 m2</u>
