Answer:
This figure is a quadrilateral, and therefore the sum of the interior angles must be 360°. Adding them up, we get 40° + 128° + x + 82° = 360°, or
168° + 82° + x = 360°, or 250° + x = 360. Subtracting 250° from both sides results in 110°, which is the measure of x.
Step-by-step explanation:
A = pi(r)^2
diameter is 18in, so radius is 9in
= pi(9)^2
A = 254.469 (round is needed)
I think it is -37m+17 but I am not sure
Answer:
350km
Step-by-step explanation:
If a map has a scale of 1: 500000, then 1 cm on the map is 500000 cm
So 7 cm on the map is 35000000 cm = 350 km
