I believe it is B because it makes the most sense
Answer:
D. sin m∠C = 2 square root of 5 all over 5
Step-by-step explanation:
The triangle ABC is a right angled triangle. The angle ∠C is where we are asked to find. The side AB measures 6 , AC measures 3 and the side BC measures 3√5.
The longest side of a right angle triangle is the hypotenuse, that means the side with length 3√5 is the hypotenuse.
Therefore side BC is the hypotenuse side and we are asked to find the angle C. AB is the opposite side while AC is the adjacent side.
Using
sin C = opposite/hypotenuse = 6/3√5 = 2/√5 = 2√5/5
cos C = adjacent/hypotenuse = 3/3√5 = 1/√5
20^2-12^2=x^2
400-144=x^2
256=x^2
x=16
Answer:
5.73 years
Step-by-step explanation:
Considering she saved 4.25% in each year of the amount $15000.
So, we have to calculate in what time her saving reaches $1275, if she save each year.
it becomes question of simple interest in which
SI = $1275, Principal P= $5000, time T, rate R = 4.25%
we know SI = PRT/100
1275 = 5000×4.25×T/100
⇒T = 1275×100/(5000×4.25)
⇒ T= 5.73 years
Answer:
Step-by-step explanation:
We have to use the slope formula: m = slope
(x1, y1) = coordinates of the first point in the line
(x2, y2) = coordinates of the second point in the line
Here, we'll plug into our given points to give; 
Solving this, we get, 
, but we're not done, as this fraction can be reduced.
Diving both sides of the fraction by 2, we get our final answer of .
