Question

If tan x = cos 45 sin45 + sin30 find x

Answer 1

tanx = cos45° sin45° + sin30°

tanx = 1 / √2 × 1 / √2 + 1 / 2

tanx = 1 / 2 + 1 / 2

tanx = 1

tanx = tan45°

x = 45°

•°• The value of x is 45°

Answer 2

Answer:

x = 45

Step-by-step explanation:

cos 45=1/√2

sin 45=1/√2

sin 30= 1/2

∴ tan x=1/√2*1/√2+1/2

=1/2+1/2

=2/2

=1

∴ Tan 45 =1

∴x = 45
