2 triangles are shown. They have one congruent side. The first triangles has angle measures of 98 degrees and 35 degrees. The second triangle has angle measures of 35 degrees and 47 degrees. Are the triangles congruent? If so, how do you know? yes, because all the angles of the triangles are acute yes, because the triangles have three congruent, corresponding angles yes, because of ASA or AAS not enough information given

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92

the answer is a) y= 2 csc [0.5 (x+pi/2)]-1
