Answer:

Answer is Area= 166.08^2

Hexagon has 6 sides

Lets focus on 1 and say the height is 8 as they look like equilateral triangles.

We cna work out shaded areas of 1/2 a triangle later to find height.

Base 1 = 8 / 2   = 4

Step-by-step explanation:

The altitude, divides the equilateral triangle into two 30^-60^-90^30∘−60∘−90∘ right triangles and divides the bottom side in half.  

In a 30∘−60∘−90∘ right triangle, the sides of the triangle equal x, x3–√, and 2x. In these equations x equals the length of the smallest side, which in our triangle is s2 or 3–√2  = 3/2

Therefore h = x square of 3

therefore x = square 3 / 2

therefore h = square 3/ 2  x  square 3/1 = 3/2

Therefore Height = 3/2 = 3.46

To find area we 1/2 base  x height

= 4 x 3.46 = 13.84 for one shaded half triangle.

12 shaded from 6 = 13.84 x 12=166.08^2

Answer:

16sqrt(3) units²

Step-by-step explanation:

This shape consists of 6 congruent triangles

Each angle = (6-2)×180/6 = 120

These are 6 equilateral triangles

6(½ × 8 × 8 × sin(60)) = 16sqrt(3) units²

How do i solve y+4=4/3(x+1)
ICE Princess25 [194]
Y + 4 = 4/3(x + 1)...first we distribute
y + 4 = 4/3x + 4/3 ...now we subtract 4 from both sides
y = 4/3x + 4/3 - 4
y = 4/3x + 4/3 - 12/3
y = 4/3x - 8/3 <======
u will have a slope of 4/3....and a  y int of (0,-8/3)...ur x int is (2,0)

in standard form, it is :
y = 4/3x - 8/3
-4/3x + y = -8/3
4x - 3y = 8....in case u need to find some points to graph

The measures of the base angles of an isosceles triangle are 3x 5 and 5x - 25. The measure of the vertex angle is 6x - 10. Find
lukranit [14]

Answer: The measure of the vertex angle = 80°

Step-by-step explanation:

Angle sum property of triangle : The sum of the measures of the angles for any triangle is 180 degrees.

So,

3x+ 5 + 5x-25+6x-10= 180\\\\\Rightarrow\ 14x-30=180\\\\\Rightarrow\ 14x= 210\\\\\Rightarrow x=\dfrac{210}{14}=15'

Then, vertex angle = 6(15)-10=90-10= 80

Hence, The measure of the vertex angle = 80°
