Answer:
The polygon with an interior angle sum of 1080° is an octagon or a polygon with 8 sides. We are given that the interior angle sum of our polygon
Step-by-step explanation:
Sorry if it's wrong.
W can be represented in the following equation: 14/tan 38°=w
Since tan 38 equals 0.78128563, we divide 14 by 0.78128563 which gives a value of 17.91
W= 17.91
W+X (which is the whole lenght) can be represented in the equation: w+x=14/tan 19°
So
17.9+X=14/0.34432761
we isolate for x and obtain
X= 40.65-17.9
X=22.75 (which we round to 22.8)
So the answer is option 4:
w = 17.9; x = 22.8
Answer:
1.5 or infinite
Step-by-step explanation:
For the second one, 8x+4=16, suppose x is 1.5 (1 1/2), then 8x1.5 is 12, then 12+4 is 16.
As for the first one, their is infinite possibilities. If x equals 3 and y is 2, then 8x3=24 and 4x2=8, and 24-8=16. Another example is if x equals 4 and y is 4. Then 8x4=32 and 4x4=16, then 32-16=16. And one final example to make sure you understand. X equals 10 and y equals 20. 8x10=80 and 4x16=64, then 80-64=16.
Answer:
C
Step-by-step explanation:
You can look them up in the graphs.
f(2) means "where is the blue graph when x=2?", and you can see it is at y=0.
Answer:
B.5
C.7
D.9
Step-by-step explanation:
a,b and c are the sides of a triangle if it satisfies:
a<b+c , b<a+c and c<b+a
Here, a=4 and b=7
We have to find c
i.e. all those c which satisfies:
4<7+c , 7<4+c and c<4+7=11
A.3 it is not true since it doesn't satisfies second inequality
B.5 it is true
C.7 it is true
D.9 it is true
E.11 This is clearly false, since it doesn't satisfies inequality third
F.17 This is clearly false, since it doesn't satisfies inequality third
Hence, correct options are:
B.5
C.7
D.9
