The sum of x and y are 116 degrees. X=54 degrees and y=62 degrees.
Explanation
==================
in point o they have 2 angles that are vertical to each other meaning that they are congruent to each other. One of the angles is 64 degrees so the other angle that is vertical to it would be 64 degrees also. So, if we have the two triangles that have 2 angles we can know the last remaining angles since the triangles would need to add to 180 degrees. In triangle 1, we have 62 degrees and 64 degrees. We add them together to get 126 and we subtract 126 from 180 degrees to get the last angle which is 54 degrees. Moving on to the next triangle. We have 64 degrees and 54 degrees. We add them together and get 118 and we subtract 118 from 180 to get 62 degrees. Now that we found out that x=54 and y-62 we add them together and we get 116.

Answer: its false
Step-by-step explanation:
Hey there!
Let us take Michael's score as ' x '
Let us take Kathryn's score as ' y '
Michael - 70 less than twice Kathryn's
x = 2y - 70
y = y
Add them, we get , 425
2y - 70 + y = 425
3y - 70 = 425
3y = 495
y = 495/3
y = 165
Kathryn's score = 165
Michael - 2 ( 165 ) - 70
= 260
Hope it helps!
Answer:
0.353
Step-by-step explanation:
We have been given that a history class is comprised of 7 female and 10 male students.
We will use combinations to solve our problem.
We can choose 6 female students out of 7 female students in ways.
We can choose 7 male students out of 10 male students in ways.
So the number of ways that 6 female and 7 males can be chose is: 7*120 = 840.
Now let us find ways in which 13 students can be chosen from 17 students as:
Now let us substitute our values in probability formula.
Therefore, the probability of selecting 6 female students and 7 male students is 0.353.
Answer:
Step-by-step explanation:
we know that
To find out the probability of hitting a ball into the circular hole, divide the area of the hole by the area of the playing area
Let
x ----> the area of the hole
y ----> the area of the playing game
so
we have
<em>Find the area of the hole</em>
The area of the circle (hole) is equal to
we have
----> the radius is half the diameter
assume
substitute
<em>Find the probability</em>
we have
substitute
