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

YOu have to set a proportion or do this easy method...
5/32= <span>0.15625
the you multiply </span><span>0.15625 by 800 because that is what you want to find out of...
that means the answer is 125

Answer is : 3x+4 the second one
Given:
18 points on her quiz
24 points is equivalent to 100%
18 is to 24 or 18/24
x is to 100% or x/100%
18/24 = x/100%
18 * 100% = 24x
1800% = 24x
1800%/24 = x
75% = x
18/24 = 75%/100%
18 * 100% = 24 * 75%
1800% = 1800%
Answer:
B
Step-by-step explanation:
using the equation 'y = 12x', if you plug in zero for 'x' you get zero for 'y'; the only graph that has the point (0, 0) is (b)
also, the x-axis represents time so, as time increases, so does the number of calories burned (which is measured on the y-axis) -- not staying flat or decreasing
