Answer:
15.6 in
Step-by-step explanation:
since this is a right triangle we can use: SOA CAH TOA
in this case, since we know the opposite and hypotenuse of 40 degrees we can use sin
sin40° = 10/x
x·sin40° = 10
x = 10/sin40°
x = 15.6
x =15.55723827
Since this is a right triangle, we can use trig functions
sin theta = opp/ hyp
sin 40 = 10/x
x sin 40 = 10
x = 10 / sin 40

Answer: x = 9
The sum of three interior angles of a triangle is 180°.
(9x - 3) + (6x) + 48° = 180°
9x - 3 + 6x + 48 = 180
15x + 45 = 180
15x = 135
x = 9
