As it is right angled , we can use pythagoras theorem.
Using the therorem :
(x+2)² + (4x+4)² = (5x)²
x² + 4x + 4 + 16x² + 32x + 16 = 25x²
25x² - 17x² - 36x - 20 = 0
8x² - 36x - 20 = 0
2x² - 9x - 5 = 0
2x² -10x + x - 5 =0
2x(x-5) + 1(x-5) =0
(x-5)(2x+1) = 0
x = 5 or x = -1/2
x cannot be -1/2 as it would make hypotenuse negative.
So x = 5
Sides are 7 m, 24 m , 25 m
The area = 1/2 × base × height
Area = 1/2 × 24 × 7 = 84 m²

Answer:
C. obtaining an even number when rolling a die
Step-by-step explanation:
Two events are independent when neither depends on the other. That is, the probability that one occurs is not affected by the occurrence, or lack of occurrence, of the other event. Their joint probability is the product of their individual probabilities.
__
Among the answer choices, all describe two independent events except C. Choice C describes one (1) event, so does NOT illustrate independent events.
