Sin 110 Degrees Find Value of Sin 110 Degrees Sin 110°

For sin 110 degrees, the angle 110° lies between 90° and 180° (Second Quadrant ) Since sine function is positive in the second quadrant, thus sin 110° value = 0 Since the sine function is a periodic function, we can represent sin 110° as, sin 110 degrees = sin (110° + n × 360°), n ∈ Z ⇒ sin 110° = sin 470° = sin 830 19 Sep 2014 如图，在菱形abcd中，∠a=110°，e，f分别是边ab，bc的中点，ep⊥cd于点p．求∠fpc的度数我来答如图，在菱形ABCD中，∠A=110°，E，F分别是边AB，BC的中点，EP⊥CD于点P．求∠

We know, however, that ∠CAE is supplementary to ∠A, since they form a linear pair We can state that m∠CAE = 180 m∠A and from ΔCAE that If we apply a trigonometric fact that sin∠A = sin(180 m∠A), we can substitute and get: (After multiplying both sides of the first equation by b) Now, substitution into the general formula for the area of a triangle ∠A= 110∘ But ∠C= ∠A {Opposite angles of a gm are equal} ∴ ∠= 110∘ But ∠A+∠B= 180∘ (Sum of adjacent angles) ⇒ 110∘ +∠B= 180∘ ⇒ ∠B=180∘ −110∘ =70∘ But ∠D=∠B (Opposite angles) ∴ ∠D=70∘ Hence ∠B= 70∘,∠C = 110∘ and ∠D=70∘ Suggest Corrections 62 Similar questions Q In a parallelogram ABCD,∠D=115o, determine the measure of ∠A and ∠B QABCD is a parallelogram in which ∠ =110∘ Find the measure

Angle Symbol (∠)

In geometry, the ∠ (angle) symbol is used to denote an angle formed by three points The middle point corresponds to the vertex at which the angle lies Typically the angle symbol is used in an expression like this: In plain language this means the angle is formed by the three points A, B, and C with the vertex at point B7 Mar 2011 所以∠A＝∠D 同理：∠C＝∠F 所以∠D＝140° 因为六边形的内角＝（62）180°＝720° 且：∠A＝140°，∠B＝100°，∠E＝90°,∠D＝140° 所以∠C+∠F=720°140°100°90°140°=250° 所以∠C=250°÷2＝125°＝＜F 评论无情天魔精致 TA获得超过1万个赞关注 ∠C=120°，∠D=140°，∠F=130°，详细过程见附图。评论 ohlanlan 如图。六边形ABCDEF中，AF平行CD，AB平行ED，∠A=140°，∠B=100°，∠E=90°。求∠C、∠D。∠
