Question

some one plz help me

Answer 1

ANSWER 5=>

As we know that sum of all the angles of the triangle is 180°.

=> 71° + 50° + (6x-1)° = 180°

=> 121° + 6x - 1 = 180°

=> 120° + 6x = 180°

=> 6x = 180° - 120°

=> 6x = 60°

=> x = 10° (Answer)

ANSWER 6=>

Again sum of all the angles in a triangle is equal to 180°.

=> 45°+ 90° + (8x +21) ° = 180°

=> 135 + 8x + 21° = 180°

=> 156° + 8x = 180°

=> 8x = 180° - 156°

=> 8x = 24°

=> x = 3° ( Answer)
