Question

5 sin square 30 degree + cos square 45 degree minus 4 Tan 30 degree by sin 30 degree into cos 30 degree + tan 45 degree​

Answer 1

Step-by-step explanation:

5 sin square 30 degree + cos square 45 degree minus 4 Tan 30 degree by sin 30 degree into cos 30 degree + tan 45 degree

=>(5sin²30+cos²45-4tan30)/sin30×cos30+tan45

=>[5(1/4)+(1/2)-4(1/√3)]/(1/2×√3/2+1)

=>(5/4+1/2-4/√3)/(3+√3)/2

=>(5√3+2√3-16√3)2

(3+√3)(4√3)

=>-18√3/(12√3+12)

=>-18√3/12(√3+1)

=>-9√3/6(√3+1)

=>-3√3/2(√3+1)
