Question

Please help me! 100 POINTS!!!!!!! Answer as fast as possible :) Please Give an explanation and an answer.

Answer 1

Answer:

If this is a normal triangle, it is impossible to solve for unique x.

However, if this is a right triangle with hypotenuse = 40 ft as shown in picture, then, by applying Pythagorean theorem, we have:

(3x)^2 + (6x)^2 = 40^2

<=> 9x^2 + 36x^2 =40^2

<=> 45x^2 =40^2

<=> x^2 = (40/45)^2

<=> x = 40/45

And the two side lengths would be :

6 x 40/45 = 6 x 8/9 = 48/9 = 16/3 = 5.3 ft

3 x 40/45 = 3 x 8/9 = 24/9 = 8/3 = 2.7 ft

Hope this helps!

Answer 2

Answer:

x = 35.6

3x = 106.7

6x = 213.3

Step-by-step explanation:

Using pythagoras theorem

(6x)² + (3x)² = 40²

36x² + 9x² = 1600

45x² = 1600

x² = 320/9

x = 35.555555

3x = 106.66666

6x = 213.3333
