Question

if angle DAB=60°, angle ABD=50°, then find angle ACB ​

Answer 1

Answer:

Given DAB=60

          ABD = 50

           ACB =?

DAB + ABD +ADB = 180 (sum of angles of a triangle is 180)

  60 + 50 + ADB    = 180

                    ADB   = 180 -110

                     ADB  = 70

From the figure we know that ADB = ACB

                          ACB = 70
