Answer:
The answer is 6-3 i
Step-by-step explanation:
It’s been awhile since I’ve done a problem like this but I believe it’s solved as below:
The area of a circle is equal to πr2. That will tell you the entire area of the circle. Then you would need to divide that by 2 to get the area of the 180° arc.
So, the area of this circle is 153.94 square meters. If you divide that by 2 (since 180° is half of a circle) you would get 76.97 square meters.
Answer:
ΔABC ≅ ΔZXN
Step-by-step explanation:
Find the letters of the matching parts of the triangles.
A is the right angle; as is Z.
B is the angle where 10 meets 26; as is X.
C is the remaining angle; as is N.

Corresponding vertices are listed in the same order:
ΔABC ≅ ΔZXN
X in litres is 67% herbicide
y in litres is 46% herbicide
{x+y=42
{0.67x+0.46y=42*0.55
{67x+46y=2310
{46x+46y=1932
21x=378
x=18 litres
