Answer:
1st answer is

2nd answer is (x, y) =(36, 45)
Lateral area = (perimeter)(height)
Perimeter = 3 + 3 + 3 = 9
Height = 6
9 * 6 = 54
Answer:
y=1
Step-by-step explanation:
4(1+2y)=12y
4*1 + 4*2y=12y
4 + 8y=12y
4=12y - 8y
4=4y
4/4=y
1=y
Complimentary angles will add up to 90 degrees
x + y = 90
x = 2y
2y + y = 90
3y = 90
y = 90/3
y = 30......this is one angle
x = 2y
x = 2(30)
x = 60.....this is ur other angle
and ur larger angle is 60 degrees
