Answer:

1. 5.3333...

2. ang ABC = 60°

ang ABD = 180°

3. 15

Answer 2

Answer:

angle ABD =120°

Step-by-step explanation:

let angle ABC =x

we know that sum of all angles of triangle =180° angle BAC+ angle ACB + angle ABC = 180°

70°+50°+ x=180°

120°+x = 180°

x= 180°-120°

x= 60°

now angle ABD =y

y+60° =180°

y=180°-60°

y= 120°

ABD = 120° ______hence proved
