For this case we have that the sum of the angles DEF and FEG is equal to 180 degrees.
Therefore, we have:

From here, we clear the FEG angle.
We have then:
FEG = 180 - DEF
Substituting values we have:
FEG = 180 - 129
FEG = 51
Then, on the other hand we have that the sum of the angles FEG and HEG is equal to 180 degrees.
Therefore, we have:
HEG + FEG = 180
From here, we clear the HEG angle:
HEG = 180 - FEG
Substituting values we have:
HEG = 180 - 51
HEG = 129
Answer:
The values of HEG and FEG are:
FEG = 51
HEG = 129
Answer:
The area of the figure is 628.3185307
Step-by-step explanation:
A= Pi*r^2
Pi*10^2= 314.15926535 (This is the answer for 2 semicircles combined)
Now you just multiply 314.15926535 by 2 to get the area of all the semicircles combined.
(314.15926535) *2 = 628.3185307
Answer:
well you do 1 divided by 2 which is 0.5
Step-by-step explanation:
Answer: The length is 8 ft and the width is 3.5 ft and those are the dimensions.
Step-by-step explanation:
The length of the rectangle is 1 more than double the width so we can represent it by the equation L = 2w + 1 where l is the length and w is the width. We know that to find the area of a rectangle, you will have to multiply the length by the width and the area is 28 ft. so we can represent it by the equation,
w(2w+1) = 28 Now solve for w to find the width
2
+ w = 28 Subtract 28 from both sides for the whole equation to equal zero.
+ w -28 = 0 Now solve for w using the quadratic formula
x= -b ±
In this case, x is representing w(the width)
a = 2 b = 1 c = -28
x = -1 ±
x= -1 ± 15 / 4
x= 14/4
x = 3.5
The width is 3.5 ft and the length is 1 more than double the width so
L = 2(3.5) + 1
L = 7 + 1
l = 8
The length is 8
Check
8 * 3.5 = 28
28 = 28
