Question

What hypotheses of a right angle triangle if ab=12 bc=9

Answer 1

Answer:

Given: In right triangle ABC

AB=12,BC=9

To find:AC

(AC)^2=(AB)^2+(BC)^2[By Pythagoras theorum]

AC^2=(12)^2+(9)^2

AC^2=144+81

AC^2=225

AC=√225

AC=15

(AC)^2=

Answer 2

ab+bc=ac
12+9=ac
21=ac
Therefore ac=21
