The value of x is 72 degrees.
60% of the total (30) can swim
60% of 30 = (60/100)*30 = 0.60*30 = 18
So 18 children can swim
This means 30-18 = 12 cannot swim
---------------------------------------------------------
An alternative is to do it this way:
We know 60% can swim so that means 40% cannot swim.
Notice how 100% - 60% = 40%
Or in other words, the 60% and 40% add to 100%. This is because we have two choices: either the person can swim or cannot swim
Since 40% cannot swim, this means
40% of 30 = (40/100)*30 = 0.40*30 = 12
and we get the same result as before
---------------------------------------------------------
Final Answer: 12
Using the same-side interior angles theorem, the values of x and y are:
x = 80
y = 130
<h3>What is the Same-side Interior Angles Theorem?</h3>
The same-side interior angles theorem states that two interior angles on same side of a transversal are supplementary.
(x - 30) and (x + 50) are same-side interior angles, therefore:
(x - 30) + (x + 50) = 180
Solve for x
x - 30 + x + 50 = 180
2x + 20 = 180
2x = 180 - 20
2x = 160
x = 160/2
x = 80
(x - 30) + y = 180
Plug in the value of x
(80 - 30) + y = 180
50 + y = 180
y = 180 - 50
y = 130

Here is you're answer:
In order to solve this answer you have to see how many centimeters are in one meter than multiple that by 75.
Therefore you're answer is "7500cm."
Hope this helps!
Answer:
Step-by-step explanation:
Given angle is 110°
Now,
From the figure,
And, as 1,2,3,4 are vertical angles and 2 = 4 = 110°
1 = 3 = 180° - 110° = 70°
