Question

PLEASE Solve this MCQ ​

Answer 1

Answer:

angle ABC =55°

Step-by-step explanation:

angle BAC + angle ABC = angle BCD

15° + 2x +3 = 5x - 60

15+3+60=5x-2x

78= 3x

x = 78/3

x= 26

angle ABC= 2x +3= 2(26) +3= 55°

Answer 2

In triangle ABC,

=> angle ABC + angle BAC = angle BCD

$= > 15 + 2x + 3 = 5x - 60$

$= > 5x - 2x = 18 + 60$

$= > 3x = 78$

$= > x = 26$

Angle ABC = 2(26) + 3 = 52 + 3 = 55°

Hope this answer helps you ^_^ !
