Answer:
- the angle at H is 120 degrees
- the missing segment is DC
Step-by-step explanation:
The "roof" FGH is bigger than 90 degrees because FG and GH are not acute. .
Without instruction we can assume FGH is 120 degree.
This means GHF is 30 degrees to complete the triangle FGH.
So the angle around H, or JHG is 90 + 30 = 120 degrees
For the ratio, we can simply look at the comparison between the small figure DJHGF
and the large figure DCBAE, and we see that the denominator
DJ in the small figure is DC in the large figure.
Painted Area: 72 in^2
Unpainted Border on all sides: ====> 4 in"
4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 = 72
Answer: =====> 66 inches
My Internet kept messing up on me here, but the Answer is 66 inches, Sorry I couldn't finish working out the problem, going to check out my internet. - Thanks - P.
Hope that helps!!!! : )
Answer:
33 degrees
Step-by-step explanation:
It is 21 degrees inside the command center and negative 12 degrees outside.
You want to find the difference between these, which means you want to subtract.
That will look like:
21 - (-12) = ?
since you have two negative signs next to each other, they will cancel each other out.
Our new equation:
21 + 12 =
21 + 12 = 33
The difference between these two temperatures is 33 degrees.
Your answer should be C. X = 12
Steps to --> 10+ 6(-9 - 4x) = 10(x - 12) + 8
10 + 6 (-9 - 4x)
= 10 - 54 - 24x
= -24x - 44
10 (x - 12) + 8
= 10x - 120 + 8
= 10x - 112
-24x = 10x - 68
-24x - 10x = 10x - 68 - 10x
-34x = -68
-34x/-34 = -68/-34
x = 2
Answer:
C) 123 cm^2
Step-by-step explanation:
well if we find CD we can cut striat down C and do area of a triangle plus the area of the rectangle.
to find CD you need length of BC
BC^2 = AC^2-AB^2 --> BC^2 = 400-100 --> BC^2 = 300
BC = 300^2 --> about 17 causeing CD being 4
now we have info
triangle area is BxHx 1/2 --> 17x10x1/2 --> 85cm^2
Now we do the small rectangle area is BxH --> 4x10 --> 40cm^2
85 + 40 = 125cm^2
the only one close is 123cm^2
