OpenStudy (song_of_the_sole):

how do i find that

OpenStudy (sshayer):

sum of angles of triangle=?

OpenStudy (sshayer):

do you know?

OpenStudy (song_of_the_sole):

no

OpenStudy (sshayer):

sum of angles of a triangle=180 degree

OpenStudy (sshayer):

can you find x?

OpenStudy (song_of_the_sole):

?

OpenStudy (sshayer):

90+43+x=180 x=?

OpenStudy (song_of_the_sole):

47

OpenStudy (sshayer):

it is simple algebra. correct

OpenStudy (song_of_the_sole):

so the answer is 47

OpenStudy (sshayer):

133+x=180 x=180-133=?

OpenStudy (song_of_the_sole):

180-133=47

OpenStudy (sshayer):

you are correct. you have to remember two things 1.sum of angles of a triangle=180 degree 2.tangent makes 90 degree with radius or diameter at its ends.

OpenStudy (song_of_the_sole):
