Question

solve: (x – 4)2 – (x + 4)2 = 48. The value of x is

Answer 1

Answer:

x=8

Step-by-step explanation:

(x-4)2 - (x+4)2 = 48

: 2 [(x-4)-(x+4)] = 48

: (x-4)-(x+4) = 48/2

: (x-4)-(x+4) = 24

: x-4-x-4 = 24

: x-x-4-4 = 24

: -8+x-x = 24

: x-x = 24+8

: x+x = 24-8

:2x = 16

:x = 16/2

: x = 8

Answer 2

Answer:

Let the first angle be x°.

And its complement angle = x° + 24°

According to question

x + x + 24° = 90°

2x + 24° = 90°

2x = 90° - 24°

2x = 66°

x = 66/2

x = 33°

Hence First angle = 33°

And complement angle = 33° + 24°

= 57°
