Answer:
4cm^2
Step-by-step explanation:
First we need to find the length of the height of the triangle using Pythagoras:
a^2+b^2=c^2 (Substitute in what we have)
a^2+3√2(^2)=2√5(^2) = a^2 + 18 = 20 -> 20-18=2 √2=BD
Now we can find the area:
AD+DC= 3√2 + √2 = 4√2 x √2 = 8/2 = 4
Answer: Angle is 3

Answer:
n = 2/3
Step-by-step explanation:
2m - 3n = 6
– 2m + 6n = 12
<u>____-____-___</u>
-9n = -6
n = -6/-9
n = 2/3
Hence, the value of n in the given equations is 2/3.
