Question

construct a right-angled triangle ABC where angle A =90 degree , BC= 4.5cm and AC= 7cm. please ans fast........ Very urgent. Pls don't give wrong answers

Answer 1

Answer and Step-by-step explanation: The described right triangle is in the attachment.

As it is shown, AC is the hypotenuse and BC and AB are the sides, so use Pytagorean Theorem to find the unknown measure:

AC² = AB² + BC²

`AB^(2) = AC^(2)-BC^(2)`

`AB =\sqrt{AC^(2)-BC^(2)}`

`AB =\sqrt{7^(2)-4.5^(2)}`

`AB =√(28.75)`

AB = 5.4

Then, right triangle ABC measures:

AB = 5.4cm

BC = 4.5cm

AC = 7cm
