Answer:
x= 8 / 5
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
20(x+2)+31=5(5x+10)+13
(20)(x)+(20)(2)+31=(5)(5x)+(5)(10)+13(Distribute)
20x+40+31=25x+50+13
(20x)+(40+31)=(25x)+(50+13)(Combine Like Terms)
20x+71=25x+63
20x+71=25x+63
Step 2: Subtract 25x from both sides.
20x+71−25x=25x+63−25x
−5x+71=63
Step 3: Subtract 71 from both sides.
−5x+71−71=63−71
−5x=−8
Step 4: Divide both sides by -5.
−5x / -5 = -8 / -5
x= 8 / 5
X + x + 36 + x + x + 36 = 360
4x + 72 = 360
4x = 288
x = 72
so the angles would be
72° , 108°, 72° , 108°.
The answer should be B using the slope formula.
xy² = x · y · y
xz = x · z
LCM(xy², xz) = x · y · y · z = xy²z
