Question

tan SQUARE 60 degrees +4 cos SQUARE 45 degrees +3 sec SQUARE 30 degrees + 5 cos SQUARE 90 degrees ​

Answer 1

Answer:

tan SQUARE 60 degrees +4 cos SQUARE 45 degrees +3 sec SQUARE 30 degrees + 5 cos SQUARE 90 degree

Answer 2

we know that,

tan60°=√3

cos45°=1/√2

sec30°=2/√3

cos90°=0

=tan SQUARE 60 degrees +4 cos SQUARE 45 degrees +3 sec SQUARE 30 degrees + 5 cos SQUARE 90 degrees

=(√3)^2+4(1/√2)^2+3(2/√3)^2+5(0)^2

=3+4(1/2)+3(4/3)+0

=3+2+4

=9
