Explanation:

From the given figure ,

AB || CD

PQ is a transversal

Given angles are 50° and 130°

50° and x are linear pair

⇛ 50°+x = 180°

⇛ x = 180°-50°

⇛ x = 130°

Therefore, "x" = 130°

and

130° and y are vertically opposite angles which are equal.

⇛ "y" = 130°

Therefore, y = 130°

Additional comment:-

If two parallel lines Intersected by a transversal then
Corresponding angles are equal.
Vertically Opposite angles are equal.
The sum of two adjacent angles is equal to 180° then they are called Linear Pair.

Can the sum of two mixed numbers be equal to 2? Explain why or why not. plz help fast

Allushta [10]

Yes. The algebraic sum of a negative mixed number and other mixed number.
-1 1/3 + x = 2
x= 2 + 1 1/3 

x = 3 1/3 

So, the algebraic sum: (-1 1/3) + 3 1/3 = 2

faltersainse [42]

To find the parameter you have to add the length and the width and multiply by two And your example long is the length and wide is the width so add it and times two answer is seven Because the semi circle is too which is what it's inside but the answer is still seven

ozzi

Answer:

Step-by-step explanation:

Mean refers to the average value of the set of data.

It is the central value of the set of data.

Another word for Mean is average.

Given scores:7, 9, 6, 3, 7, 8, 4, 10, 7, 9

Solution:

Sum of observations = $7+ 9+ 6+ 3+ 7+ 8+ 4+ 10+ 7+ 9=70$
