10. 884.222 (2 is recurring)
15² =225
20²= 400
225+400=625
25² =625
=> 15² +20² =25²
These three form a Pythagorean triplet..
And hence form a Right triangle with 25 as the hypostenuse....
Answer is option 4
Hope it helps...

The number of tickets to sell at the door is 48 tickets.
<u>Step-by-step explanation</u>:
- Cost of play at the door = $5
- Cost of play in advance = $4
- The theater club wants to raise at least $400 from the play.
- Number of tickets sold in advance = 40 tickets.
Let 'x' be the number of tickets need to sell at the door.
5x + 4(40) = 400
5x + 160 = 400
5x = 240
x = 240/5
x = 48 tickets
The number of tickets to sell at the door is 48 tickets.
Step-by-step explanation:
<AOF and <COD are vertical angles.
m<AOF = m<COD = 80°
Angle Addition Postulate m<BOF - m<AOF = m<AOB
m<AOB = 135° - 80° = 55°
