2a.
Since BC = 10m and M is the midpoint, we can find CM by : 10÷2 = 5m
So, CM = 5m
2b. Now, you have the base ( 5m) & hypotenuse (13m). Pythagoras' Theorem:

Where c is the hypotenuse, a & b are sides.

b here refers to the height.
2c.
Area of a right-angled triangle =

So,
Answer:
X = 30
Step-by-step explanation:
20^2 + 23^2 = x^2
400 + 529 = x^2
929 = x^2
√929 = √x^2
X = √929
X = 30.48
Answer:
zero slope
Step-by-step explanation:
horizontal lines are zero slope because they are not slanted (slope)
this is a horizontal line.
Answer:
∴At the beginning of the game Sparrow had = (70+12)=82 coins
Step-by-step explanation:
Given , three pirates named Ahab, Sparrow and Davy play a game.
Let at the end of the game Ahab, Sparrow and Davy have 4x, 5x,and 6x coins respectively.
Total number of coins= 4x+5x+6x=15x
Again given that the pirates have a total of 210 coins.
According to the problem,
15x =210
⇔x = 14
Therefore, Ahab, Sparrow and Davy have(4×14)=56,(5×14)=70 and (6×14)=84 respectively.
Since,Ahab has won 5 coins and Davy has won 7 coins.This(7+5)=12 coins was belonged to Sparrow.
∴At the beginning of the game Sparrow had = (70+12)=82 coins
Answer:
Alex timed 7 by 2 instead of 7 times 7 because 7^2 is an exponent.
