The answer is HJ , just got 100 on the quiz :)
Answer:
B
Step-by-step explanation:
So remember that a quarter of a circle is 90 degrees, a half of a circle is 180 degrees, and a whole circle is 360 degrees.
Looking at the image shown, it must be half a circle, whihc is 180 degrees. The image tells us that the 1st angle is 7 degrees. Now, we must find the 2nd angle.
Heres what we know however:
angle 1 + angle 2 = 180 degrees.
How do we know this?
Well, there are only 2 angles in this 180 degrees. We know that the first one is 7 degrees.
Lets input that into our nice lil equation to get an answer:
7 degrees+angle 2 = 180 degrees
Now lets solve.
Subtract 7 on both sides, and your left with:
angle 2 = 173 degrees.
So the answer must be:
<u>173 degrees</u>
Hope this helps! ;)
Answer:
11
Step-by-step explanation:
I think you just add the ratios together.
Hello!
In order to create a complete triangle, the sum of the two smaller sides must be greater than the largest side. This can be expressed using the following formula:
(S1) + (S2) > (S3)
We'll begin by inserting the first set of values into the inequality above:
3 + 6 > 10
Simplify the left side:
9 > 10
The inequality (9 > 10) is false. Therefore, the first set of values can be eliminated. Now complete the same process for the next set of values:
3 + 6 > 9
9 > 9
The inequality (9 > 9) is false. Therefore, we can eliminate the second set of values as well. Now complete the same process for the third set of values:
4 + 6 > 9
10 > 9
The inequality (10 > 9) is true. Therefore, we can confirm the third set of values (4 ft - 9 ft - 6ft) as a valid answer.
I hope this helps!
