Question

Evaluate 5 sin
5 sin 2 30 cas ² 45° +4 tan boo​

Answer 1

Step-by-step explanation:

I hope the question is,

5sin^2(30)+cos^2(45)-4tan^2(30)*2sin(30)*cos(30)+tan(45)

=5*(1/4)+(1/2)-4*(1/3)*2*(1/2)*(root3/2)+1

=(5/4)+(2/4)-(2/root3)+1

=11/4-(2*root3)/3

=

(11 \div 4) - (2 \sqrt{3} \div 3)

=1.595
