4) Here both smaller and larger triangle is "isosceles" in nature.
So, sum would be 180 with two equal sides.
66 + BDE + BED = 180
2 BDE = 180 - 66
BDE = 114 / 2
BDE = 57
<span>In short, Every four angles would be equal to 57
</span>5) A) 7
It is because it must be smaller than the longest side which is equal to 8
6) D) Yes, Because ∠C is congruent to ∠BED
Hope this helps!
If we call y the height of the plane, we know when the time (x) is 0, the height is 30000. So let's write that in:
y = 30000 + (0)
Then, for every increase of a minute (x increases by 1), the height reduces by 2000. This can be written as:
y = 30000 - 2000x
Using what we know about y = mx+c equations, the slope of the line is -2000, and the y-intercept is (0, 30000).
Answer:
O 0.5 units
Step-by-step explanation:
so the first thing we have to do is to calculate for the dilation factor. Taking point G as the reference point, we can see that the distance of point G from rectangle W'X'Y'Z is 1.5 while the distance from rectangle WXYZ is (1.5 + 7.5) = 1.5 / 9 = 1/6
Since WX has an initial measure of 3 units, therefore the measure of W'X' is:
W'X' = 3 units *(1/6) = 0.5 units
Answer: 2/3 feet
Step-by-step explanation:
6 1/6 - 5 1/2
6 1/6 - 5 3/6
5 7/6 - 5 3/6 = 4/6 or 2/3
2/3 feet is the difference in their heights.
Answer:
The value of x is 30 and y is 14
Step-by-step explanation:
Here, In given triangle,
∆JLK is similar to ΔPQR
JL is corresponds to PQ.
So, we have the ratio, 21/y ...(1)
Now,
LK is corresponds to QR.
So, we have the ratio, 18/12 = 3/2 ...(2)
Now,
JK is corresponds to PR.
So, we have the ratio, x/20 ...(3)
Then, (1) = (2) = (3)
21/y = 3/2 = x/20 ...(*)
Now, Cross Multiply by (1) and (2) we get,
21 × 2/y × 3
42 = 3y
3y = 42
y = 42/3
y = 14
Here, we get the value of y is 14. So, we will put the value of y in (1) we get,
21/y = 21/14
So, by (*) we get
21/14 = 3/2 = x/20
Then, Cross Multiply with (2) and (3) we get,
3/2 = x/20
20 × 3 = 2 × x
60 = 2x
2x = 60
x = 60/2
x = 30
Thus, The value of x is 30 and y is 14
<h3><u>FOR</u><u> </u><u>VERIFICATION ONLY</u><u>:</u><u>-</u></h3>
21/y = 3/2 = x/20
21/14 = 3/2 = 30/20
3/2 = 3/2 = 3/2
