Question

40 POINTS Can anyone answer question 8 only e ii and iii please

Answer 1

Answer:

ii)  c = 4    iii) c = 8

Step-by-step explanation:

A = x axis intercept = 1/2 c

B = y axis intercept = c

ii)  Area of a triangle = 1/2 x base x height

                               4 = 1/2 x (1/2)c x c

                              c² = 16

                                c = 4

iii)  2√5 will be the hypotenuse of a right-angled triangle with base 1/4 c and height 1/2 c

(2√5)² = (1/4 c)² + (1/2 c)²

      20 = 1/16 c² + 1/4 c²

      20 = 5/16 c²

         c² = 64

          c = 8
