Step-by-step explanation:
A straight line adds up to 180°
m+3m=180°
4m=180°
m=45°
3m=45°
angle CBD=3(45)
=135°
4m = 12x + 40
8x + 8x + 12x + 40 + 4m = 360
28x + 40 + 12x + 40 = 360
x = 7
m = 12(7) + 40 = 124
-x+y=3
y=x+3
2x + x + 3 =6
3x + 3 = 6
3x = 3
x = 1
-1 + y = 3
y = 4
2(1) + y = 6
2 + y = 6
y = 4
Solution: (1, 4)
Answer
Front yard is 20 square root 5 back yard and height is 40 square root 5
Step-by-step explanation:
1. set up A=1/2 H(b1+b2)
2. 6000=1/2 2x (2x+x)
3. 12000=6x^2
4.2000 = x^2
5. x=20 square root 5
