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:
402 days.
Step-by-step explanation:
f(x)=1+1.5ln(x+1)
When f() = 10 we have:
10 = 1 + 1.5ln (x + 1)
ln (x + 1) = (10-1) / 1.5 = 6
x + 1 = e^6
x = e^6 - 1 = 402.4.
Answer:
24-3x
Now, Putting the value of x=5
= 24-3×5
=24-15
=9

Answer:
14 miles
Step-by-step explanation:
Assuming each horse was only ridden once
then a total of 13 horses were ridden for a total of 182 miles
182 miles
/ 13 horses = 14 miles horse
Of course, if each horse was ridden more than once before being replaced the distance between replacements could be reduced.
Note that the fact that there were 3 riders is irrelevant.
Answer:
7 hours
Step-by-step explanation:
78-15=63
63 divided by 9= 7
