Question

Abcd is a rhombuss such that acb =40°then adc is _

Answer 1

Answer:

100

Step-by-step explanation:

we let say ABCD is a rhombus,

given angle ACB=40

so angle CAB also 40 because all sides are equal that means AB=BC becomes an isosceles triangle

so the third angle which is ABC = 100

by using angle sum property in a triangle

and we know rhombus is parallelogram so opposite angles are equal

so angle ABC= angle ADC

so ADC=100
