Question

(ii) In the figure, ZABC = 90°, AB = 3x, BC = 4x and AC = 30, then
(a) Using Pythagoras theorem, determine the value of x.
(b) Find the length of segments AB and BC.
(c) Find A (A ABC).​

Answer 1

Answer:

Step-by-step explanation:

∠ABC = 90°, AB = 3x, BC = 4x and AC = 30, then

AB = base

BC = perpendicular

AC = Hypotenuse

Using Pythagoras theorem, determine the value of x.

H² = P² + B ²

30² = 4x² + 3x²

900 = 16x² + 9 x²

900 = 25 x²

900 / 25 = x²

36 = x²

√36 = x

6 = x

the length of segments AB and BC.

AB = 3x

= 3 × 6

= 18

BC= 4x

= 4 × 6

= 24
