The question is four parts, It is required the angles of <span>parallelogram KLMN

</span><span>

</span>So, It is required ⇒ ∠K , ∠L , ∠M and ∠N

See the attached figure which represents the explanation of the problem

========================

Part (1): Find ∠N:

==============

in the shape FLDN

<span>∵ LF ⊥ KN ⇒⇒⇒ ∴ ∠LFN = 90°</span><span>

</span>∵ <span>LD ⊥ NM ⇒⇒⇒ ∴ ∠LDN = 90°</span><span>

</span>∵ The sum of all angels of FLDN = 360°

∵ <span>∠FLD = 35°</span><span>

</span>∴ ∠FLD + <span>∠LDN + ∠DNF + </span><span>∠LFN = 360°</span><span>

</span>∴ 35° + 90° + <span>∠DNF + 90° = 360°</span><span>

</span>∴ ∠DNF = 360° - ( 90° + 90° + 35°) = 360° - 215<span>° = 145°

</span>

**∴ The measure of angle N = 145°**=============================

Part (2): Find ∠M:

==============

∵ KLMN is <span>parallelogram , ∠N = 145°</span>

∴ The angles N and M are supplementary angles ⇒ property of the parallelogram

∴ ∠M + ∠N = 180°

∴ ∠M = 180° - ∠N = 180° - 145° = 35°

**∴ The measure of angle M = 35°**

================================

Part (3): Find ∠L:

==============

∵ KLMN is parallelogram , ∠M = 35°

∴ The angles N and M are supplementary angles ⇒ property of the parallelogram

∴ ∠M + ∠KLM = 180°

∴ ∠KLM = 180° - ∠M = 180° - 35° = 145°

OR ∠KLM = ∠N = 145° ⇒⇒⇒ property of the parallelogram

**∴ The measure of angle KLM = 145°**===================================

Part (4): Find ∠K:

==============∵ KLMN is parallelogram , ∠N = 35°

∴ The angles N and M are supplementary angles ⇒ property of the parallelogram

∴ ∠K + ∠N = 180°

∴ ∠K = 180° - ∠N = 180° - 145° = 35°

OR ∠K = ∠M = 35° ⇒⇒⇒ property of the parallelogram

**∴ The measure of angle K = 35°**
