Question

Find the value of
sin 30°xcos²30°+cos 60° x sin square 60°
3 tan²30° + tan square
60​

Answer 1

Answer:

20

Step-by-step explanation:

Answer 2

2cosec²30° + x sin²60° – 3/4 tan²30° = 10

—› (2×2²) + (x ×√3/2²) – (3/4 × 1/√3²) = 10

—› (2×4) + (x × 3/4) – ( 3/4 × 1/3) = 10

—› 8 + 3/4x – (9+4)/12 =10

—› 3/4x = 10 – 8 + 13/12

—› 3/4x = 2 + 13/12

—› 3/4x = (26 + 13)/12

—› 3/4x = 39/12

—› x = 39/12 ÷ 3/4

—› x= 39/12 × 4/3

—› x = 13/3

So, The value of x is 13/3
