Question

i need some help please

Answer 1

@Vocaloid

Answer 2

my guess is that it's somewhere in the 60's or below, but i dont know a definitive answer

Answer 3

MA = 80.5 - 35

then you just set up a ratio between corresponding sides of the big triangle and the smaller triangle at the top, such that

MA/MN = x/MP

Answer 4

so 1.14?

Answer 5

@Vocaloid

Answer 6

check your calculations again

(80.5-35)/80.5 = x/96.6

Answer 7

0.56?

Answer 8

cross multiplying gives us

0.565217 = 0.010352x
x = about 54.6

Answer 9

do i mostly do the same thing as the last one?

Answer 10

same thing as last time. the sides of the small triangle are proportional to the big triangle

so 6/(6+48) = 5/(5 + 3x + 7)

Answer 11

11

Answer 12

good, 11 = your solution

Answer 13

eh I had to look this up but according to the angle bisector theorem BD/DC = AB/AC

so x/3 = 3.2/4 i think?

Answer 14

x=2.4?

Answer 15

yeah that's what i got too

Answer 16

same logic as last time (x+4)/58 = 55/63.8

Answer 17

46

Answer 18

yeah that's what i got too

Answer 19

a leg of a triangle **can never** be longer than the hypotenuse

remember, hypotenuse^2 = leg^2 + leg^2, solve for the other leg

Answer 20

12.6?

Answer 21

good

Answer 22

good

Answer 23

hm check the way you set up your proportion. you can also visually insepct that x must be in the 40-60 range-ish

(46.2-14)/46.2 = x/72.6

Answer 24

50.6

Answer 25

good

Answer 26

check the set up again

11/(11+121) = 10/(10+5x+10)

Answer 27

20

Answer 28

good

Answer 29

actually nvm if you use triangle proportionality theorem that's right

Answer 30

alright

Answer 31

if we let WZ = x, then YW = (8-x) and the proportion becomes x/(8-x) = 6/6.5

Answer 32

idk why they tell you not to round your answer though, I don't think the answer is rational

Answer 33

3.84?

Answer 34

yeah that's what i got too

Answer 35

almost

x/4 = 4.5/5

cross multiplying gives us

5x = 18

x = 18/5 = 3.6 not 3.5

Answer 36

princeeve question ?

Answer 37

@Vocaloid pardon for your interfer but i think there is something wrong

Answer 38

bc. BD is angle bisector so this mean that divide the side AC in two equal parts

Answer 39

given that BD is angle bisector and not altitude

Answer 40

so my opinion that AD = DC = 4

Answer 41

an angle bisector does not necessarily divide the opposite side in two congruent segments.

Answer 42

anyway for this next problem you just have to set up the angle bisector proportion again

62/(x+2) = 99.2/112

Answer 43

68?

Answer 44

good

Answer 45

good

Answer 46

I'm really not supposed to help with these, just check to make sure to plugged everything in the pythagorean theorem correctly and you should be ok

Answer 47

being a unit test and all

Answer 48

fair enough

Answer 49

well, i got a good grade on it anyway, i still have some more tests to makeup, if you still would like to help

Answer 50

alright

Answer 51

set up a ratio btwn corresponding sides

38/15.2 = 55/x

Answer 52

that's 22?

Answer 53

awesome, 22 = your sol'n

Answer 54

hm check again

small triangle long leg/small triangle short leg = big long leg/big short leg

(3x+1)/12 = 4x/(12+3)

Answer 55

5?

Answer 56

good

Answer 57

is x 21?

Answer 58

hm i don't think so

using triangle proportionality i get
39/26 = x/18

Answer 59

27, so i was close

Answer 60

good guess but they share one similar side, the angle in between (the angle at the top of the triangle) and the right side

so SAS

Answer 61

hm, pqr doesn't work (for AA to work both triangles must have the same angle)

as a hint try calculating the missing angle in MNO

Answer 62

so the first answer?

Answer 63

good

Answer 64

check again, you are given no angles so you cannot use sas

Answer 65

so SSS

Answer 66

good

Answer 67

the big triangle is three times the small triangle so 39 = 3(x-10) solve for x

Answer 68

23 then

Answer 69

ah sorry got distracted by work

that's correct

Answer 70

9/(2x+4) = 6/(x+4) i think

Answer 71

4?

Answer 72

good

Answer 73

alright, thank you.
