0.21 would be rational,because it is a terminating decimal,which means that it has an ending point and can be converted into a fraction.ur welcome
y = -2/-3x + 4/-3
y= ⅔x -4/3
if the line is parallel them m =⅔
so u have
y-5/x-4 = ⅔
3y-15= 2x-8
3y-2x =-8+15 = 7
-2x+3y=7 or 2x-3y=-7this is the standard form
while y= ⅔x +7/3 is the intercept form
<span><span>if one angle is x and the ratio of 1 : 4 : 7, means second angle is 4x and third angle is 7x
since the sum of all three angles in a triangle is 180 degrees, we have
x+4x+7x=180
12x = 180
x = 15
then
4x = 60
7x = 105
The angles are 15°,60 °, and 105 °.</span><span>
Therefore, yes.</span></span>
Your answer is 22 because line segment CD has 22 units which is parallel to AD
