Answer:

Step-by-step explanation:

It is close, but not exactly a right triangle.

If it were a right triangle, we would have ...

21² +70² = 73²

We have instead ...

441 +4900 ≠ 5329

5341 ≠ 5329 . . . . . . . . not a right triangle

Answer:

Step 3 contains error.

Step-by-step explanation:

The given equation is :

$\dfrac{1}{4}(\dfrac{1}{3}k+9)=6$

Step 1.

Cross multiplying,

$(\dfrac{1}{3}k+9)=24$

Step 2.

Subtract 9 from both sides

$\dfrac{1}{3}k+9-9=24-9\\\\\dfrac{1}{3}k=15$

Step 3.

Cross multiplying

$k=15\times 3\\\\k=45$

So, there is an error in step 3. The correct answer should be 45.
