Answer:
x=1.4 or 21/15
Step-by-step explanation:
45x+angle trs = 180 straight line
angle trs = 180-45x
angle trs + angle t + angle tsr = 180 (sum of angles in a triangle =180)
(180-45x) + 25x + 57+x = 180
combine like terms
180 +57 -45x+25x+x=180
237-19x=180
subtract 237 from each side
-19x =-57
divide by -19
x=3
Answer:
f^-1 (9) = 7 equals f = 9/7
Step-by-step explanation:
f^-1 x 9 = 7, f ≠ 0
1/f x 9 = 7
9/f = 7
9 = 7f
7f = 9
