In general, the sum of the measures of the interior angles of a quadrilateral is 360. This is true for every quadrilateral. This does not help here, because there are two angles (angles B and D) we know nothing about. We only know about opposite angles A and C.
In this case, you can use another theorem.
Opposite angles of an inscribed quadrilateral are supplementary.
m<A + m<C = 180
3x + 6 + x + 2 = 180
4x + 8 = 180
4x = 172
x = 43
m<A = 3x + 6 = 3(43) + 6 = 135
Answer: 135 deg
Find the relationship of 1’s in the given number.
given number = 911 147 835
before we are going to determine the relationship of 1’s , let’s give each digit’s place value.
9 hundred million
1 ten million
1 million
1 hundred thousand
4 ten thousands
7 thousands
8 hundreds
3 – tens
5 - ones
Now, we have the 1 ten million, 1 million, and 1 hundred thousand
What is the relationship of the 3.
=> we’ll those 1’s are 10 times greater with each other
=> 1 million is 10 times greater than 1 hundred thousands
=> 100 000 x 10 = 1 000 000
=> 1 ten million is ten times greater than 1 million
=> 1 000 000 x 10 = 10 000 000
Answer:
4/7 = 40/70
3/10 = 21/70
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
Lets dissect the dot plot for information:
1 point = 1 time
2 points = 2 times
3 points = 3 times
7 points = 1 time
8 points = 3 times
9 points = 1 time
10 points = 1 time
Total number of times he gets extra credit points is:
1 + 2 + 3 + 1 + 3 + 1 + 1 = 12 times
Out of which "3" was 3 times
and "7" was 1 times
That would make it
3 + 1 = 4 times
So, out of 12 times in total he gets extra credit points, 4 times is "3" or "7". In percentage, that will be:
4/12 = 0.3333
Multiplying 0.3333 * 100 = <u>33.33%</u>
<u>Answer choice A</u>
