SOLUTION
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

Answer:
Step-by-step explanation:
2(cosec²30)+x(sin²60)-3/4tan²30=10
2*2*2+x*√3/2*√3/2-3/4*1/√3*1/√3=10
8+3x/4-3/4*1/3=10
3x/4-3/12=10-8
3x/4-1/4=2
3x/4=2+1/4
3x/4=9/4
x=4*9/3*4
x=3 ans
