Question

find angle ABC in the given fig​

Answer 1

Step-by-step explanation:

so your answer is 55 degree

Answer 2

Answer:

here we can see...

ACD is a straight line,

therefor angle ACB + angle DCB = 180

=> angle ACB = 180 - angle DCB

=> angle ACB = 180 - (5x -60)

= 240 - 5x

now, in ΔABC

angle BAC + angle ACB + angle CBA = 180

=>15 + (2x + 3) + (240 - 5x) = 180

=> -3x = 180 - 258

=>3x = 78

=> x= 26

angle ABC is (2x +3) = 2 X 26 + 3

= 52 + 3

= 55

Hence, angle ABC is 55° .
