Answer:
75°
Step-by-step explanation:
In triangle FBG, one angle is 36. That means the other two must total 180-36=144. Assigning each one 72, their supplementary angle on the interior of the pentagon would be 108.
In triangle JDI, one angle is 39. That means the other two must total 180-39=141. Assigning each one 70.5, their supplementary angle on the interior of the pentagon would be 109.5
We now have 4 of the interior angles. Pentagons have an interior total of 540. 540-108-108-109.5-109.5=105
x is the supplement of 105. 180-105=75
Answer:
square units
Step-by-step explanation:
The simple formula we need here is:
Where
d is length of diagonal
s is length of side of square
Let's find side length of square from information given:
Now,
we know area of square is
We know s, and now we find area
Area =
The first answer choice is right, 1/2x^2 sq. units.
3.5*8=28
The answer is 28 m^3
