Answer:
3
Step-by-step explanation:
all same signs means positive
Answer:
The angle the running and the skateboarding path ≈ 51.2°(to the nearest tenth)
Step-by-step explanation:
The course takes the shape of a triangle. That means it has three sides.
One side of the triangle(biking path) = 51 meters , another side(skateboarding) = 64 meters . The angle opposite the skateboarding path = 78°. The angle opposite the biking path is what we are ask to find.
Using sine rue we can find the angle opposite the biking path which is the angle between the running and skateboarding path. Note we used the sine rule because 2 sides are given and a non included angle
a/sin A = b/sin B = c/sin C
51/sin A = 64/sin 78°
cross multiply
51 sin 78° = 64 sin A
sin A = 51 sin 78°/64
sin A = (51 × 0.97814760073) /64
sin A = 49.8855276374/64
sin A = 0.77946136933
A = sin⁻¹ 0.77946136933
A = 51.2112853091
A ≈ 51.2°(to the nearest tenth)
Since, this is parallelogram
so, opposite sides are equal
We will find value of sides
Calculation of AB:
we are given point A=(-2,3)
point B=(4,0)
we can use distance formula
now, we can plug values
Since, this is parallelogram
so, opposite sides are equal
so,
Calculation of AD:
point A =(-2,3)
point D=(-5,2)
we can use distance formula
now, we can plug values
Since, this is parallelogram
so, opposite sides are equal
so,
Calculation of AE:
point A=(-2,3)
point E=(-3,1)
we can use distance formula
now, we can plug values
(a)
we know that
perimeter of a parallelogram is sum of all sides
so,
perimeter is
now, we can plug values
