Answer is :
cos⁻¹[(-1-4√7)/(√17, √8) = 173.33° ≈ 173°
The answer would be 8 dogs.
First, let's list the lengths of the sides in descending order.
Lengths of sides of quadrilateral ABCD: 20, 18, 14, a
Lengths of sides of quadrilateral EFGH: b, c, 6, 5
From the listings above, we see that he sides measuring 14 and 6 are corresponding.
We are looking for c which corresponds to 18.
14 is to 6 is as 18 is to c
14/6 = 18/c
7/3 = 18/c
7c = 3 * 18
7c = 54
c = 54/7 = 7 5/7
Answer: 7 5/7 feet
If perimeter is 60 so the side is 60 ÷ 3 = 20
Now we can apply the area formula for triangles;
Answer:
C
Step-by-step explanation:
the only it has constant rate of change (slope, gradient or derivative at every point is equal)
