Answer:
Length of diagonal is 18 m
Step-by-step explanation:
Given in trapezoid ABCD. AC is a diagonal and ∠ABC≅∠ACD. The lengths of the bases BC and AD are 12m and 27m. We have to find the length of AC.
Let the length of diagonal be x m
In ΔABC and ΔACD
∠ABC=∠ACD (∵Given)
∠ACB=∠CAD (∵Alternate angles)
By AA similarity theorem, ΔABC~ΔACD
∴ their corresponding sides are proportional

Comparing first two, we get
⇒ 
⇒ 
⇒ 
hence, the length of diagonal is 18 m
A store manager is redesigning a display shelf. The width of an individual deodorant is 2.576 inches
Width of each deodorant = 2.576 inches
We need to store 25 individual deodorants side by side
Width of 1 deodorant = 2.576 inches
Width of 25 deodorant = 2.576 * 25 inches= 64.4 inches
The shelf must be 64.4 inches wide to store 25 individual deodorants side by side
Answer:
199.96 feet
Step-by-step explanation:
The base of the ultra-modern store is of a round shape.
The area of the base is 31416 square feet.
We have to find the diameter of the base.
Now, the area of a circle is given by
⇒
⇒
⇒
feet.
Therefore, diameter = 2r = 199.96 feet. (Answer)
2t<-4 divide both sides by 2
t<-2
...
7t>49 divide both sides by 7
t>7
So t=(-oo,-2) and t=(7,+oo)
t=(-oo,-2)U(7,+oo)
Answer:
20 degrees
Step-by-step explanation:
If QS bisects Angle PQR, it would mean that Angle PQS and Angle RQS are equal
2x+6=5x
Subtract 2x on both sides
6=3x
Divide by 3 on both sides
x=2
Plug the value of x into either one of the angle measures equation
5x
5(2)=10
If they are equal to one another it would mean that the other angle would be the same measure and you would multiply it by 2
10(2)=20
Therefore 20 degrees is the answer for the measure of Angle PQR
