Question

Find BAC, ACD
and ABE​

Answer 1

Answer:

=> BAC = 180° - (BCE + ABC)

= 180° - (90° + 70°) [BCE is 90° because angles in a semicircle are 90°]

= 180° - 160°

= 20°

=> ABE = 180° - (BAE + BEA)

= 180° - (60° + 90°) [BEA is 90°, because angles in a semicircle are 90°]

= 180° - 150°

= 30°

=> ACD = 180° - BAD

= 180° - (BAC + CAD)

= 180° - (20° + 30°)

= 180° - 50°

= 130°

[Sum of opposite angles in a quadrilateral is 180°]
