Question

In a pentagon ABCDE,angle B=168°,angle C:angleD=23:25 and AB||ED. Find angle C and angle D. ​

Answer 1

Answer:

∠C = 92

∠D = 100

Step-by-step explanation:

since AB║DE, adding exterior angles at B,C,D = 180

(180-B)+(180-C)+(180-D) = 180

∠B+∠C+∠D = 360

168 + 23x + 25x = 360

48x = 192

x = 4

∠C = 92

∠D = 100
