The hypotenuse of right triangle is 52 centimeters long. The difference between the other two sides is 28 centimeters.

KiRa [710]

Answer:

The length of the perpendicular = 20 meters

The length of the base = 48 meters

Step-by-step explanation:

The hypotenuse of the triangle = 52 meters

Let the Length of the perpendicular is = k meters

So, the length of the base = ( k + 28) m

Now, by PYTHAGORAS THEOREM , in a right angled triangle:

$(BASE)^{2} + (PERPENDICULAR)^{2} = (HYPOTENUSE)^{2}$

⇒ Here, $(k)^{2} + (k +28) ^{2} = (52)^{2}$

Also, by Algebraic Identity:

$(a+b) ^{2} = a^{2} + b ^{2} + 2ab\\ \implies (k+28) ^{2} = k^{2} + (28) ^{2} + 2(28)(k)\\$

So, the equation becomes:

$(k)^{2} +k^{2} + (28) ^{2} + 2(28)(k) = (52)^{2}$

or, $2k^{2} + 784+ 56k = 2704\\\implies k^{2} + 28k - 960 = 0$

or, $k^{2} + 48k -20 k - 960 = 0$

Solving the equation:

⇒ (k+48)(k-20) = 0 , or (k+48) = 0 , or (k-20) = 0

or, either k = -48 , or k = 20

As k is the length of the side, so k ≠ - 48, k = 20

Hence, the length of the perpendicular = k = 20 meters

and the length of the base is k + 28 = 48 meters

stepladder [879]

Answer:

1) 1.28 times greater or 127.29% greater

2) 7.43 billion

3) 8679 years

4) 125.45g

Step-by-step explanation:

8.3/6.5=1.2769

5(1+2/100)^20

=5(1.02)^20

=7.429735

Qr=Qi(1/2)^(t/Ht)

35=100(0.5)^t/5730

=8678. 5 years

Qr=300(0.5)^2000/1590=300x0.418

Qr=125.4489
