ummm I think I know but I don't at the same time take away 40 from 112 and theres you answer♥.
Answer:
x=81
y=99
z= 129
Step-by-step explanation:
the 3 angles of a triangle add to 180 degrees
51 + 48 + x = 180
99 + x = 180
subtract 99 from each side
99 + x -99 = 180 -99
x = 81
x+y = 180 they make a straight line
81+ y = 180
subtract 81 from each side
y = 180-81
y = 99
z+ 51 = 180 they make a straight line
subtract 51 from each side
z+51-51 = 180 -51
z = 129

Answer:
Step-by-step explanation:
cos A = 36/45 = 4/5 answer is C
sin A = 27/45= 3/5
tan A = 27/36= 3/4
sec A = 45/36= 5/4
csc A = 45/27= 5/3
cot A = 36/27= 4/3
