A. 35°

B. 90°

C. 45°

D. 55°

Answer 1

do you know what angle measure hase a line ?

Answer 2

no

Answer 3

geometry is hard

Answer 4

there are line a and line b

line b is perpendiculare on line a

yes ?

Answer 5

i guess

Answer 6

there are two right angles formed by line b

yes ?

Answer 7

yeah

Answer 8

a right angle how many degree has ?

Answer 9

90

Answer 10

exactly so than there are two how you get the angle measure of a line ?

Answer 11

180

Answer 12

very nice

Answer 13

so whats nexts

Answer 14

moment i like tech you step by step

Answer 15

teach

Answer 16

ok

Answer 17

so than you see on this drawn Park st. is perpendiculare on Main st. yes ?

Answer 18

yes

Answer 19

so this angle what make Park st. with Main st. make an angle with 90 degrees

ok

than you see on this figure given that tis angle has 35 degrees

yes ?

Answer 20

yes so 35 is the answer

Answer 21

no

moment

than you see this figure on the right part there are 3 angles

from what 3 you know the measures of two

yes ?

Answer 22

yes i guess

Answer 23

there up is the right angle with 90 degree and bottom the given measure angle with 35 degrees

Answer 24

90 - 35

Answer 25

no

you know again that a line has 180 degrees

yes ?

Answer 26

180-90-35

Answer 27

not exactly

you get the measure of midle angle than you substract the sum of these two angles one from the top and one from bottom so from 180

ok ?

Answer 28

idk whats next

Answer 29

assume 90 with 35 and what you get substract from 180

Answer 30

180-35

Answer 31

no

i ve wrote

180 - (90+35) = ?

Answer 32

courage

Answer 33

125

Answer 34

180-125

Answer 35

yes very nice so how many is this ?

Answer 36

55

Answer 37

but the other question the answer was 55

Answer 38

moment

so there you ve got now that the measure of midle angle is 55 degrees

yes ?

Answer 39

yes

Answer 40

ok

so than you remember on your past math problem the reflexive congruencie property of two angles and you see this given figure how you think that is the midle angle from the right part and the angle formed by Park st. with Oak st. ?

Answer 41

check please the given image

Answer 42

so not are congruent angles ?

Answer 43

yes

Answer 44

so what result from this ?

Answer 45

umm

Answer 46

idk

Answer 47

why not ?

you said above that they are congruent angles

and you know that the measure of midle angle from the right part has 55 degrees

so what result from this ?

Answer 48

its 55

Answer 49

excatly

Answer 50

the answer is 55

Answer 51

perfect

Answer 52

ok thank you i will have more question coming

Answer 53

was hard ?

Answer 54

i think you understand it now and hope that was easy so step by step

yes ?
