Question

If
sin 135º - cos 240°/sin135°+cos240°=a+√b,then b=​

Answer 1

Answer:

a = 0; b = 2;

Step-by-step explanation:

sin 135° - cos 240°

sin 135° + cos 240°

= a + √b

add both

2 sin 135° = a + √b

(135 = 180 - 45)

2sin (180 - 45) = a+ √b

2sin 45° = a+√b

2 × 1 / √2 =  a+√b

0 + √2 =  a+√b

a = 0

√b = √2 ⇒ b = 2
