Answer:

h = 55

Step-by-step explanation:

the sum of the 3 angles in a triangle = 180°

the 2 unknown interior angles = 180 - 2h ( straight angle ), hence

the sum of the 3 angles

180- 2h + 180 - 2h + 40 = 180

400 - 4h = 180 ( subtract 400 from both sides )

- 4h = - 220 ( divide both sides by - 4 )

h = 55

Find the area of a regular hexagon with side length 10 m. Round to the nearest tenth.

Maksim231197 [3]

Answer:

$A=259.8\ m^2$

Step-by-step explanation:

we know that

The area of a regular hexagon is the same that the area of 6 equilateral triangles

The area of 6 equilateral triangles applying the law of sines is equal to

$A=6[\frac{1}{2}b^2sin(60^o)]$

where

b is the length side of the regular hexagon

we have

$b=10\ m$

substitute

$A=6[\frac{1}{2}(10)^2sin(60^o)]$

$A=259.8\ m^2$
