Assuming you mean sqrt(-144, we can use some properties of square roots to figure this out. sqrt(x*y) = sqrt(x) * sqrt(y)
We have sqrt(-1*144) = sqrt(-1) * sqrt(144). That would be i * 12, which is 12i.
Answer:
= 70 Meters
Step-by-step explanation:
We can use the sine rule as follows:
Angle ABC=180-(70.5+38.833)
=70.667°
Using the sine rule and sides AB, AC and angles ABC and ACB:
b/Sin B=c/Sin C
Replacing with the values above we get:
AC/Sin ABC= AB/Sin ACB
105.6/Sin 70.667=AB/Sin 38.833
AB=(105.6 Sin 38.833)/Sin 70.667
=70.17 meters
The distance between the two points to the nearest meter is 70 meters
6m x 10m for the rectangle part.
Then the triangle is base x height/2=3 x 7/2= 21/2
But we have two of the same triangle, so we multiply 21/2 by 2, giving us 21.
21 + 60= 81m^2
Hope you get it!
Wait is that the actual problem??
