The correct answer is the last option: 9,40,41
 
 Explanation:

1. The hypotenuse of the triangle is the larger side. Keeping this on mind, you must apply the Phytagorean Theoream, as below:
 
 a²=b²+c²
 
 "a" is the hyptenuse and "b" and "c" are the legs of the right triangle.
 
 2. Then, you have:
 
 a=41
 b=40
 c=9
 
 3. If you apply the formula above to calculate the hypotenuse and the result is 41, then those are the lengths of sides of the right triangle. Therefore:
 
 <span>a²=b²+c²
</span> a=√<span>b²+c²
</span> a=√(40)²+(9)²
 a=√1600+81
 a=41

Answer:

No, they are not. While they are similar terms, they do not have the same values within the terms. Like how 3 is not -2.

If sin = 3/5 and 0 &lt;= x &lt;= pi/2 , find the exact value of tan 2θ.
Alexxandr [17]

For starters,

tan(2θ) = sin(2θ) / cos(2θ)

and we can expand the sine and cosine using the double angle formulas,

sin(2θ) = 2 sin(θ) cos(θ)

cos(2θ) = 1 - 2sin^2(θ)

To find sin(2θ), use the Pythagorean identity to compute cos(θ). With θ between 0 and π/2, we know cos(θ) > 0, so

cos^2(θ) + sin^2(θ) = 1

==>  cos(θ) = √(1 - sin^2(θ)) = 4/5

We already know sin(θ), so we can plug everything in:

sin(2θ) = 2 * 3/5 * 4/5 = 24/25

cos(2θ) = 1 - 2 * (3/5)^2 = 7/25

==>  tan(2θ) = (24/25) / (7/25) = 24/7

Which statements must be true?
slamgirl [31]

Answer:

The options 2,3 and 5 are correct.

Step-by-step explanation:

From the figure it is noticed that the points U,V and W are midpoint of JK,KL and JL respectively.

Midpoints theorem of triangle states that the line connecting the midpoints of two sides is parallel to third side and its length is half of the third side.

The points U and W are midpoint of JK and JL. Using midpoint theorem, we get

UW=\frac{1}{2}KL

UW\parallel KL

The points U and V are midpoint of JK and KL. Using midpoint theorem, we get

UV=\frac{1}{2}JL

UV\parallel JL

The points V and W are midpoint of KL and JL. Using midpoint theorem, we get

VW=\frac{1}{2}JK

2VW=JK

VW\parallel JK

Therefore options 2, 3 and 5 are correct.
