Look at the picture.

a) 180° - 45° = 135°

b) Use trigonometric function

$\tan(\angle DBA)=\dfrac{45}{30}\\\\\tan(\angle DBA)=1.5\\\\m\angle DBA\approx56^o$

270° - 56° = 214°

Answer:

${ \sf{( \sec \theta - \csc \theta)(1 + \tan \theta + \cot \theta) }} \\ = { \sf{( \sec \theta + \tan \theta \sec \theta + \cot \theta \sec \theta) - ( \csc \theta - \csc \theta \tan \theta - \csc \theta \cot \theta)}} \\ = { \sf{( \sec \theta + \sec \theta \tan \theta + \csc \theta) - ( \csc \theta - \sec \theta - \csc \theta \cot \theta)}} \\ = { \sf{ \sec \theta \tan \theta + \csc \theta \cot \theta }} \\ { \bf{hence \: proved}}$

Sin tita + sin ^2 tita = 0

AnnyKZ [126]

Answer:

tita = 0 , 180, 270, 360. ( tita = 0 ≤ x ≤ 360).

Step-by-step explanation:

sin tita + sin ^2 tita = 0

sin tita( sin tita + 1) = 0

sin tita = 0, - 1.

For angles between 0 and 360 inclusive sin = 0 gives 0, 180 and 360 degrees. The angle whose sine is -1 is 270 degrees.

tita = 0 , 180, 270, 360.
