In ΔNOP, o = 64 inches, p = 83 inches and ∠N=168°. Find the area of ΔNOP, to the nearest square inch.

Step-by-step explanation:

\text{Area of a Triangle}\rightarrow \text{S.A.S.}

Area of a Triangle→S.A.S.

\text{Area}=\frac{1}{2}ab\sin C

Area=  

2

1

​

absinC

From reference sheet.

\text{Area}=\frac{1}{2}(64)(83)\sin 168

Area=

1

​

(64)(83)sin168

Plug in values.

\text{Area}\approx552.213\approx 552

Area≈552.213≈552

Evaluate and round.

552

552

Step-by-step explanation:

Area of a Triangle→S.A.S.

Area=1/2 ab sin C

area = 1/2 (64)(83) sin 168

area=552.213=552

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this

can i get the link to the assignment?
