Answer:
x = 27
Step-by-step explanation:
∠ CAD and ∠ EDF are corresponding angles and are congruent, so
∠ CAD = 2x
The sum of the 3 angles in Δ ABD = 180°
sum the angles and equate to 180
72 + 2x + 2x = 180
72 + 4x = 180 ( subtract 72 from both sides )
4x = 108 ( divide both sides by 4 )
x = 27
850
All you do is times 425 by 2
425×2
850
hope this helps
You would use 1.07 for that
3x+2y=50
x+y=19
x=12, y=7
12 jumps, 7 "raise the roof"s
