Answer:
29 degrees
Step-by-step explanation:
Given
<D = 2x+8
<A = 122
The sum of the adjacent angle of the trapezoid is 180 degrees
<D + <A = 180
2x + 122 = 180
2x = 180-122
2x = 58
x = 58/2
x = 29 degrees
Hence the value of x is 29 degrees
Answer:
.25, .012, .001
Step-by-step explanation:
Divide the length by 1000
25÷1000= .25
12÷1000= .012
1÷1000= .001
Proportional is the relationship two numbers share. for instance, 3 : 6. for every three, there is six. for every one, there is two.
a table would be proportional if the top numbers and the bottom numbers corresponds, such as 1 on the top and 2 on the bottom. it would continue like 2 : 4, so on and so forth.
you can tell if fractions are proportional by using cross multiplication.
Perpendicular lines meet each other always at an angle of 90 while intersecting lines may or may not have an angle of 90.
Their opposite angles(made by intersecting lines) are always same.
And even, we can say every perpendicular lines as intersecting but can't say that every intersecting line is perpendicular.
