Answer:
True ( A )
Step-by-step explanation:
4 ( 5 ) - 2 = 2 ( 5 ) + 8
20 - 2 = 10 + 8
18 = 18
This is a correct statement because 18 does equal 18

Step-by-step explanation:
The 3 angles add up to 180 degrees
2y + 2y + 5y = 180
9y = 180
Answer:
The length of BE is 5.5 units.(A correct option)
Step-by-step explanation:
Given diameter AC intersects chord BD at point E such that AE = 2.5 units and DE = 3.4 units. Point O is the center of the circle, and the radius of the circle is 5 units. we have to find the approximate length of BE.
CE=CO+OE=5+(OA-AE)=5+2.5=7.5 units.
Now, by Intersecting Chord Theorem which states that when two chords intersect each other inside a circle then the products of their segments are equal.
⇒ ![CE\times AE=BE\times DE](https://tex.z-dn.net/?f=CE%5Ctimes%20AE%3DBE%5Ctimes%20DE)
⇒ ![7.5\times 2.5=BE\times 3.4](https://tex.z-dn.net/?f=7.5%5Ctimes%202.5%3DBE%5Ctimes%203.4)
⇒ ![BE=\frac{7.5\times 2.5}{3.4}=5.5147\sim5.5units](https://tex.z-dn.net/?f=BE%3D%5Cfrac%7B7.5%5Ctimes%202.5%7D%7B3.4%7D%3D5.5147%5Csim5.5units)
Hence, the length of BE is 5.5 units.
