Answer:
<h2>if the sum of the two angles is 90°,then they are said to be <u>complementary angles.</u></h2>
Answer:
For x=7 and y=9 Caleb and Eva will meet again. That is, Caleb will have made 7 labs and Eva 9 labs.
Step-by-step explanation:
In order to find the number of labs that Caleb and Eva must complete, to meet again at the start, you can use the following equation:
(1)
where x is the number of labs made by Caleb and y the number of labs made by Eva. The equation (1) means that for the specific values of x and y, Caleb and Eva will spend the same amount of minutes on the labs.
Then, you need to find the least integers values of x and y.
First, you solve the equation (1) for y:
(2)
By inspection you can find that the least value of x that makes possible that y is an integer, is 7
In fact, you have:
Hence, for x=7 and y=9 Caleb and Eva will meet again. That is, Caleb will have made 7 labs and Eva 9 labs.
ANSWER
The distance is 10 units.
EXPLANATION
Let us use the distance formula to find the distance between,
and
The distance formula is given by,
We plug in the values to get,
A = first angle, b = 2nd angle, c = 3rd angle
a = 2b
c = b + 80
a + b + c = 180
2b + b + b + 80 = 180
4b + 80 = 180
4b = 180 - 80
4b = 100
b = 100/4
b = 25 <=== 2nd angle
a = 2b
a = 2(25)
a = 50 <=== 1st angle
c = b + 80
c = 25 + 80
c = 105 <=== 3rd angle
