we know that
An <u>acute triangle</u> is a triangle with all three angles acute (less than 
).
An <u>obtuse triangle</u> is one with one obtuse angle (greater than ) and two acute angles.
A <u>right triangle</u> is one with one right angle (angle equal to ) and two acute angles.
therefore
The answer is
Is not possible
Answer: 0
Step-by-step explanation:
The probability of event A happening, then event B, is the probability of event A happening times the probability of event B happening given that event A already happened.
In this case, event A is the Captain hitting the pirate ship and event B is the pirate hitting the Captain's ship.
The Captain fires first, so his ship can't be sunk before he fires his cannons.
So, the probability of the Captain hitting the pirate ship is 2/5
If the Captain hit the pirate ship, the pirate has no chance of firing back.
So, the probability of the pirate hitting the Captain's ship given the Captain hitting the pirate ship is 0.
Okay this dude will do it ¥ the guy around me with the answer
I
Heptagon, it is a polygon with seven sides and seven vertices
Answer:
Therefore solution for a is
Step-by-step explanation:
Given:
7a - 2b = 5a + b
To Find:
a = ?
Solution:
7a - 2b = 5a + b .................Given
First take all the 'a' terms to the left hand side and 'b' terms to the right-hand side of the equation,
∴ 
Now dividing by 2 on both the side we get
∴ 
Therefore solution for a is
