We need to find the hypotenuse of the triangle. We can find that by using the Pythagorean theorem: a² + b² = c²
Solve with the given values of the triangle:
2² + 4² = c²
4 + 16 = c²
20 = c²
√20 = √c²
4.47 ≈ c
Find the area of the square using: A = bh
4.47 * 4.47 = 19.9809
Therefore, the area of the square is approximately 19.9809units²
Best of Luck!
Sin Ф=opposite/ hypotenuse
In this case:
sin 25º=9 in /c
c=9 in/ sin 25º
c≈21.3 in.
Answer: sin (25º), in this case can be used to find the lenght of the hypotenuse, and the length of this hypotenuse would be 21.3 in.
We know that
Based on the table
Percent%=[1-Decay factor]*100%
so
for decay factor=0.98
Percent%=[1-0.98]*100%----> 2%
for decay factor=0.50
Percent%=[1-0.50]*100%---->50 %
for decay factor=0.64
Percent%=[1-0.64]*100%----> 36%
for decay factor=0.23
Percent%=[1-0.23]*100%----> 77%
therefore
the answer is
36%
