Answer:
w = -12
Step-by-step explanation:
w/6 + 5/8 = -1 3/8
Subtract 5/8 from each side
w/6 + 5/8-5/8 = -1 3/8 - 5/8
w/6 = -1 3/5 - 5/8
w/6 = -1 8/8
w/6 = -2
Multiply by 6 on each side
w/6 *6 = -2*6
w = -12
Cos(40)= 21/ (hypotenuse)
hypotenuse(cos(40))= 21
hypotenuse = 21/ cos(40)
21/ cos40 = 27.41
The answer is ∠BED by vertical angles theorem.
2(2x-1) + 2(3x)=4x-2+6x = 10x - 2 & not <span>=10x-1</span>
