I dont really understand this question, i really would of liked to help.
A right triangle ABC is formed when we join three points around a lake. Length of the side AC = 6 miles. Length of the side BC = 2 miles. We have to find Length of side AB.Using Pythagorean theorem for Right triangle ABC , Right angled at B→AB² + BC²= AC²→ AB² + 2²= 6²→ AB² = 36 - 4→ AB²= 32→ AB = √ 32→→AB = 5.66 (approx)Option (B) AB = 5.66 is Right choice.
4781=1781+125t
solve the equation for t to get
T=24 years
So the answer is
1940+24=1964
Answer c
Cosecant = 1/sin so it is where sin =0. Out of these sin is 0 at 180 degrees
