Answer 1

any idea ?

Answer 2

No

Answer 3

so you know that sinus of an angle is equal opposite side divide hypothenuse ,right ?

Answer 4

yeah

Answer 5

than what can you writing for angle E using sinus of E ?

Answer 6

opposite side divide hypothenuse = 6/10

right ?

Answer 7

so = 0,6

Answer 8

thats not a choice

Answer 9

yes because this is numericaly but you need getting in degree ,yes ?

Answer 10

yes

Answer 11

you know the numericaly values of different basicaly angles like sin45, or sin60 ,... sin30

???

Answer 12

sin45=sqrt2 /2

do you know it ?

Answer 13

sqrt2 = approximatly 1,41

yes ?

Answer 14

so 1,41/2 = 0,7

Answer 15

so i dont know what are these choises but i think that from these calculi result that angle E has a measure of 45 degree

Answer 16

the choices are 24,53,37, and 10 so thats not it

Answer 17

so than you can calculi it again using

sinE= 0,6 so this mean E=arcsin(0,6)

can you calculi it or do you have any exemple in your mathbook how you get this in degree ?

Answer 18

yes using googgle i have got arcsin(0,6)=36,86 degree

so what mean that angle E has a measure of 37 degree

Answer 19

ok ?

Answer 20

i just did it on oole thanks :)

Answer 21
