Answer:

\boxed{Yes.}

Step-by-step explanation:

To solve this equation, we can use the Pythagorean Theorem: a^2 + b^2 = c^2, where a and b are regular side lengths and c is the hypotenuse.

  • The hypotenuse is the longest side of a triangle and is assigned to the c-variable.
  • The other two side lengths can be assigned to either a or b because of the commutative property: a + b = b + a.

Now, just substitute the side lengths into the formula and solve!

9^2 + 12^2 = 15^2    Simplify the equation by taking each value to its power.

81 + 144 = 225    Simplify by adding like terms.

225 = 255

Therefore, this is indeed a right triangle.

Answer:

<h2>Yes, this is a right triangle.</h2>

Step-by-step explanation:

Hypotenuse always have the highest number than base and perpendicular.

Hypotenuse ( h ) = 15

Base ( b ) = 9

Perpendicular ( p ) = 12

Let's see whether the given triangle is a right triangle or not

Using Pythagoras theorem:

{h}^{2}  =  {p}^{2}  +  {b}^{2}

Plugging the values,

{15}^{2}  =  {12}^{2}  +  {9}^{2}

Evaluate the power

225  = 144 + 81

Calculate the sum

225 = 225

Hypotenuse is equal to the sum of perpendicular and base.

So , we can say that the given lengths of the triangle makes a right triangle.

Hope this helps..

Best regards!!

Which is more 2/3 or 2/4
goblinko [34]
The answer would be 2/3 is greater than 2/4. Two- thirds is equivalent to 0.67 while 2/4 is equivalent to 1/2 or 0.5. Of course, 0.67 is greater than 0.5.

I think the answer would be C. based on the cost of the treatment alone, plan A should be selected over plan B

If we count the cost and probability of remission, the cost of per 1 % remission with plan A is $ 25 , while the cost of per 1 % remission with plan B is $ 34
