U can find the reciprocal of a number by flipping the number.
example : the reciprocal of 1/5 is 5/1....the reciprocal of 2/3 = 3/2.
the reciprocal of x = 2/7.....that means x = 7/2
5 / (7/2) = when dividing fractions, flip what u r dividing by, then multiply
5 * 2/7 =
10/7 or 1 3/7 <==

Answer:
Step-by-step explanation:
A)1st pair: ∠HKJ ,∠JKG 2nd pair: ∠HKE,∠EKF
B)Verticle angle:∠HKE and ∠GKF
C) 4x+5+41=180
4x+46=180
4x=134
x=33.5
D)4x+36=90
4x=90-36
4x=54
x=13.5
E) x+x-4=180
2x=184
x=92
Answer:
The number of ways in which students were chosen is 45 ways .
Step-by-step explanation:
Given as :
The number of students in a class = x = 10
The number of students chosen by teacher to go to library = y = 2
Let The number of ways in which students were chosen = n ways
<u>Now, According to question</u>
So, number of ways in which students were chosen = 
Or, n ways = 
Or, n = 
Or, n = 
Or, n = 
Or, n = 
Or, n = 5 × 9
i.e n = 45
So, The number of ways in which students were chosen = n = 45 ways
Hence,The number of ways in which students were chosen is 45 ways . Answer
