Question

HELP I DO NOT UNDERSTAND

Answer 1

Answer:

72° and 14°

Step-by-step explanation:

ABDE is a circular quadrilateral so sum of opposite angles are 180° . So AED=72° .

In ∆ADB , BDA=180-(108+50)=22°

In ∆ADE , AD=DE ,so AED=EAD=72°

Finally in ∆EAC

EAC=72+22=94° , AEC=72° ,

SO

Angle ECA=x=180-(72+94)=14°
