One of the same side angles of two parallel lines is 20° smaller than the other one. Find all angles.
Answers
Answer:
80°, 100°
Step-by-step explanation:
Suppose line AB and CD are parallel to each other, and lint GH intersect both at point L and M.
Now for same side interior angles of parallel lines, we know that
"sum of same side interior angles is 180° or they are supplementary angles"
Now, ∠DML + ∠BLM = 180°
∠M = x
∠L = y
Since, one angle is 20° less than second,
y=x-20
So we can make an equation,
x + y =180
x+x-20=180
2x-20 = 180
2x = 180-20
2x = 160
x = 160/2
x = 80°
Hence, y = 100°
Answer: 80 and 100
Step-by-step explanation:
180/2=90
90+10=100
90-10=80

Answer: Useful tools in teaching kids to read a clock include a working analog clock with the minutes marked off either by ones or by fives, from zero to 60; a play-clock that allows you to move the minute hand to show any time; and printouts of clocks with the hours divided into "pizza slices" at each big number.

So is .Special note: Why is it OK to have 0 on top (in the numerator) and not on the bottom (in the denominator)?Consider for a moment what division means. The reason that is because 2·5 = 10.The fraction because 2·0 = 0.The fraction can't equal anything. There is no number you can multiply by 0 and get 10 as your answer. The fraction is undefined.What about ? It's undefined, too, but for a slightly different reason. If you multiply the 0 in the denominator by any number at all you get the 0 in the numerator. It seems that can equal any number. As a result we say is indeterminate, which is a special kind of undefined expression.B.

Answer:
1080
Step-by-step explanation:
looking at the ratio of 1 : 3 : 6, we can say that the pupils are divided into 1 + 3 + 6 = 10 "parts".
Indian are 1 part, Malay are 3 parts, and Chinese are 6 parts.
So 3x (3 parts of malay) is 360 more than 1x (1 part of Indian). Thus:
3x - 360 = x
2x = 360
x = 180
We know chinese is 6 parts, or 6x, so Chinese would be 6 (180) = 1080
Hence, there are 1080 chinese pupils
