Exercise 5 Part 1
Calculate by justifying the measurement of angles: CAD and CDA
B
45
432
35.35
Part 2
1) give the value of BD 92
2) show that AD = V50
3) show that AC = 50
3) calculate the exact value of CD
30
Part 3
Check that x is the difference between the perimeters of triangles ABC and ABD
Part 4
1) Give the exact value of the area of ​​ABD then that of ACD
2) Complete with the exact value then approximate: area of ​​ABD =
X area of ​​ACD​

f is the midpoint of

32/80  

91/140

the last one 54 doesn't go into 45. 54/100 ?

step-by-step explanation:

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
