Answer 2

Answer:

a) ( 15x + 6) = 96°

Reason : Vertically opposite angles

So let us solve this ,

15x = 96 - 6

15x = 90

x = $\dfrac{90}{15}$

x = 6

Thus , 15x + 6 = 15 × 6 + 6

= 90 + 6 = 96

Hence it is correct

b ) ( 2x + 50 ) = 100°

Here too these angles are vertically opposite so ,

= 2x = 100 - 50

= 2x = 50

= x = $\dfrac{50}{2}$

= x = 25

Now , 2×25 + 50 = 50 + 50

= 100

Hence this is the correct answer
