Question

if fig BC and CE of triangle BCE produced to A and D respectively.if angle ECA =120 degree and angle DEB =145 degree . find angle EBC and angle BCE ?​

Answer 1

Answer:

EBC =60°

BCE=85°

Step-by-step explanation:

Angle ECA+ Angle ECB = 180° (Linear Pair)

120+ Angle ECB= 180°

ECB= 180-120

= 60°

Angle DEB + Angle BEC =180° (Linear Pair)

145+ Angle BEC=180

Angle BEC= 180-145

= 35°

Angle BCE + Angle CEB + Angle EBC =180 ( angle sum property of triangle)

60°+35°+ Angle EBC =180

Angle EBC = 180-95

=85°
