in right angle ABC,what is the length of altitude drawn from the vertex A to BC?
(PLEASE ANSWER IT I WILL RATE U 5 AND I'LL THANK YOU IF U ANSWER CORRECTLY)

Answer:
Mathematicians seek and use patterns[8][9] to formulate new conjectures; they resolve the truth or falsity of such by mathematical proof. When mathematical structures are good models of real phenomena, mathematical reasoning can be used to provide insight or predictions about nature. Through the use of abstraction and logic, mathematics developed from counting, calculation, measurement, and the systematic study of the shapes and motions of physical objects. Practical mathematics has been a human activity from as far back as written records exist. The research required to solve mathematical problems can take years or even centuries of sustained inquiry.
Step-by-step explanation:
In this right angled triangle ΔABC, length of the altitude drawn from vertex A is the leg AB itself. By Pythagoras theorem. AC2 = AB2 + BC2 132 = AB2 + 122 169 = AB2 + 144 AB2 = 169 – 144 = 25 AB2 = 52 AB = 5cm
