Answer:
72
Step-by-step explanation:
The interior angles of a 6 sided figure add to (n-2) * 180
where n is the number of sides
(6-2) *180
4*180
720
2x+4x+4x+4x+4x+2x = 720
20x = 720
Divide by 20
20x/20 = 720/20
x =36
We want <F
<F = 2x = 2*36 = 72
If g(x) is a reflection of f(x) over the x axis, then g(x) = -1*f(x), which can be shortened to g(x) = -f(x). We stick a negative outside the entire f(x) function to flip the signs of each y coordinate. For example, if the point (1,2) was on f(x), then (1,-2) is on g(x).
So f(x) = 5(0.8)^x turns into g(x) = -5(0.8)^x
Answer: Choice B
Answer:
118.3 m²
Step-by-step explanation:
The area (A) of a triangle is
A = bh ( b is the base and h the perpendicular height )
Note the legs 13 and 18.2 are at right angles to each other, hence
A = 0.5 × 13 × 18.2 = 118.3
Answer:
c=-25
Step-by-step explanation:
-3(-c-18)=-3-18
3c+54=-21
3c=-21-54
3c=-75
c=- 75/3
=-25
