Jul 14, 2020 · AC=13cm. AD=13,9cm. Step-by-step explanation: a)Pythagoras' Theorem in ABC, right-angle triangle. AC²=AB²+BC². AC²=144cm²+25cm²=169cm². AC=13cm. b)ACD is right …
ABCD is a rectangle with AB =5 cm and diagonal AC =13 cm Find …
Mar 19, 2023 · ac =13cm. To Find, The perimeter of the rectangle abcd. Solution, abcd is a rectangle. side ab = 5cm. ac = 13cm (diagonal of the rectangle) Using Pythagoras theorem. ac² = ab²+bc². ac =13cm. ab = 5cm. 13² = 5² + bc². 169= 25 +bc². bc² =169 -25. bc² = 144. bc =√144. 12cm. Rectangle abcd's two sides. ab= 5cm. bc = 12cm. Therefore, the ...

Explain why length of AC is 13cm. calculate length of AD
AC is opposite the right angle, so it is the hypotenuse. Use the Pythagorean theorem. (AB)^2 + (BC)^2 = (AC)^2 (12 cm)^2 + (5 cm)^2 = (AC)^2 144 cm^2 + 25 cm^2 = (AC)^2 (AC)^2 = 169 cm^2 AC = 13 cm b) Now we look at triangle ACD. Angle ACD is the right angle. The legs measure 13 cm and 5 cm. We need AD, the length of the hypotenuse. (AC)^2 ...

ΔABC is an isosceles triangle with AB = AC = 13cm. The length of altitude from A on BC is 5cm. Find BC. It is given that Δ ABC is an isosceles triangle. Suppose the altitude from A on BC meets BC at D. Therefore, D is the midpoint of BC. Δ 𝐴𝐷𝐵 𝑎𝑛𝑑 Δ 𝐴𝐷𝐶 are right-angled triangles. A B 2 = A D 2 + B D 2. B D 2 = A B 2 - A D 2 = 13 2 - 5 2.
