Answer:

tanC = 3/4

Step-by-step explanation:

by Pythagoras theorem first find the line DE =

36^{2}+DE^{2}=45^{2}

-> DE=27

then we know that tanθ=opposite/adjacent

so, 27/36 =tanC

simplified: tanC = 3/4

1. Find the HCF of the following numbers by prime factorisation and continued division method10,35,40​
statuscvo [17]

Answer:

Step-by-step explanation:

10 = 2*5

35 = 5*7

40 = 2*2*2*5

The number 5 is common to all three  factorisations

So the HCF = 5.

Continued division:

10 and 35:

 10) 35(3

       30

          5)10(2

              10

                0

- so the HCF of 10 and 35 is 5.

10 and 40:

10)40( 4

     40

        0  

So the HCF of 10 and 40 is 10

We found HCF of 10 and 35 is 5 so:

HCF of 10, 35 and 40 is HCF of 5 and 10 which is 5.

Pareto Chart

Step-by-step explanation:

Given chart is missing (Attached)

Find:

- Which chart represents the correct data.

- What other chart can be used to express the given data

Solution:

- Use the given values for each color and compare with the three charts A,B and C given.

                For Blue =    A (12)    ,    B(12)    ,    C(11)

                For Green = A(7)       ,    B(13)    ,    C(12)

- Hence,  The chart A is correct.

- Any other chart which can correctly express the information given should be a chart that uses bars or frequency to expresses the percentages. Pareto Chart expresses both bars and line chart(curve) to express the frequency of the data.
