Answer:
35%
Step-by-step explanation:
The percent change is calculated as
× 100%
change = 222.75 - 165 = 57.75, thus
% change =
× 100% = 0.35 × 100% = 35%
Step-by-step explanation:
the slope is the ratio "y coordinate difference / x coordinate difference".
so,
(2 - 6) / (x - 2) = 4/7
-4 / (x - 2) = 4/7
-1 / (x - 2) = 1/7
-1 / (x - 2) = 1 / -(x - 2) = 1/7
-(x - 2) = 7
-x + 2 = 7
-x = 5
x = -5
so, the point is (-5, 2)
Answer:
6. 135°
7. 135°
Step-by-step explanation:
You have to assume that the figure is a regular octagon, so has central angles equal to exterior angles equal to 45°.
6. A regular anything is circumscribed by a circle, so the measure of any inscribed angle is half the measure of the corresponding central angle. That is, ∠BET =∠TBA = (45°)/2, so their sum is 45°. ∠BOT is the supplement of that, 180° - 45° = 135°.
__
7. ∠GIT + ∠ITS is the same measure as one internal angle of the octagon. That is the supplement of the exterior angle we identified above as being 45°.
∠GIT + ∠ITS = 135°
Hopefully I am correct but it is 12x÷x-2
Answer:
x=1
