Answer:8:30 PM (20:30) Previous Day
Step-by-step explanation:
Answer:
128 deg
Step-by-step explanation:
The sum of the measures of the angles of a polygon of n sides is
(n - 2)180
A trapezium has 4 sides, so the sum of the measures of the angles is
(4 - 2)180 = 2(180) = 360
<em>m<CBE + m<C + m<D + m<DEB = 360</em>
Angles ABC and CBE are a linear pair so the sum of their measures is 180 deg.
m<ABC + m<CBE = 180
115 + m<CBE = 180
m<CBE = 65
m<C = x
m<D = 90
Angles DEB and DEF are a linear pair so the sum of their measures is 180 deg.
m<DEB + m<DEF = 180
m<DEB + m<103 = 180
m<DEB = 77
<em>m<CBE + m<C + m<D + m<DEB = 360</em>
65 + x + 90 + 77 = 360
x + 232 = 360
x = 128
Answer: 128 deg
<em />
Step-by-step explanation:
force 1 x distance 1= force 2 × distance 2
therefore 600n x 2m = 400n x distance 2
1200Nm = 400N x distance 2
1200Nm ÷ 400N = distance 2
the two netwons will cancel out each other so the answer is 3m
Answer:
x = -9
Step-by-step explanation:
let the number = x
So x ÷ -3 = x + 12
Mulitply both sides by -3: x = -3x -36
Add 3x to both sides: 4x = -36
Divide both sides by 4: x = -9
