Answer:
the inverse is 9x + 18
Step-by-step explanation:
switch 'x' with 'y'
y = 1/9x - 2
x = 1/9y - 2
solve for y now, start with multiplying each side by 9
9x = y - 18
y = 9x + 18
f^-1(x) = 9x + 18
Step-by-step explanation:
The total internal angle of the polygon is 360°. Since there are 4 unknown angles but the same, we would just add all those to 60° to equal a full 360°.

Answer:
68.09cm²
Step-by-step explanation:
area = √(s * (s - a) * (s - b) * (s - c))
√(21.5* (21.5 - 10) * (21.5 - 14) * (21.5 - 19))
=68.088
*round*
=68.09
