Answer 1

y= 10

Explanation:

we have to find x first

∠ABD= 90° because its a right angle

3x°=90°

divide by on both sides

x= 30°

∠CBD must equal 90° degrees as well because a line is 180°

60+3y= 90

-60

3y=30

/3

y= 10

Answer 2

y=10 x=30

Explanation:

3x=90

x=30

2(30)+3y=90

60+3y=90

3y=30

y=10
