Answer:
4
Step-by-step explanation:
H (height the 2x4 contact the fence)
sin 30° = H / 8
1 /2 = H / 8
H = 1/2 * 8 = 4
Answer:
1. d
2. a
Step-by-step explanation:
Thats how it goes!
Branliest plzzz
Wa=0.5Wb, Ha=20, Hb is unkown
the area of rectangle a is : Wa*20
the area of rectangle b is : Wb*Hb
Rectangle a has 7 times the area of rectangle b: Wa*20=7*Wb*Hb
Replace Wa with 0.5Wb: 0.5Wb*20=7Wb*Hb => Hb=10/7
Thats when point =0. equation of a line mx +b where m is the slope
and b is the intercept
I think it’s d because that’s where the z would come from with the AEC right angle.
