construct a right-angled triangle ABC where angle A =90 degree , BC= 4.5cm and AC= 7cm. please ans fast........ Very urgent. Pls
Katena32 [7]

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 =\sqrt{28.75}

AB = 5.4

Then, right triangle ABC measures:

AB = 5.4cm

BC = 4.5cm

AC = 7cm

If this figure is a regular figure? How many degrees does each angle measure?
bearhunter [10]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

\frac{(5 - 2) \times 180}{5}  =  \\

\frac{3 \times 18 \times 10}{5}  = 3 \times 18 \times 2 =  \\

54 \times 2 = 108

Thus each angle has a measure of 108° degrees.
