FULL EXPLANATION REQUIRED.​

Answer 1

Answer: 1.3

Step-by-step explanation: As, it's a Right triangle we can follow PYTHAGORAS THEORUM which says H^2 = P^2 + B^2

So, let the base be x metre. Then,

8.5^2 = 8.4^2 + x^2

8.5^2 - 8.4^2 = x^2  (TRANSPOSING)

(8.5-8.4)(8.5+8.4) = x^2         (a^2 - b^2) = (a+b)(a-b)

(16.9)(0.1) = x^2

1.69 = x^2

1.3 = x

So, the value of x is 1.3m
