Answer:
Step-by-step explanation:
2y = -4x + 8
y = -2x + 4
perp. 1/2
y - 2 = 1/2(x - 6)
y - 2 = 1/2x - 3
y = 1/2x - 1
Answer:
x=20
Step-by-step explanation:
First, find LJ
Angle L = 60 (180 - 30 - 90)
The cosine of an angle is equal to the ratio of the adjacent side to the hypotenuse.
cos(L)=adj/hyp
cos(60)=LJ/40√2
LJ = cos(60)*40√2
LJ = 20√2
Now you can use LJ to find x. You also know the value of each angle, 45
x=20√2⋅cos(45)
x=20
