The area of the triangle PQR is 6.5 unit square.

<h3>What is defined as the triangles?</h3>

Triangles are three-sided polygons with three vertices.

  • The angles of the triangle are established by connecting the three sides end to end at a point.
  • The sum of the triangle's three angles corresponds 180 degrees.

The three coordinates of the points are P(4,6), Q(8,5), and R(5,9).

The formula for the area of the triangle when the coordinates are given is;

area of ΔABC = (1/2)[x₁(y₂ - y₃) + x₂(y₃ - y₁) + x₃(y₁ - y₂)]

(x₁, y₁) = P(4,6)

(x₂,y₂) = Q(8,5)

(x₃, y₃) = R(5,9)

Put the given values in the formula;

area of ΔABC = (1/2)[4(5 - 9) + 8(9 - 6) + 5(6 - 5)]

On solving;

area of ΔABC = (1/2)[-16 + 24 + 5]

area of ΔABC = (1/2)[13]

area of ΔABC = 6.5

Therefore, the area for the triangle formed by the coordinates is 6.5 unit square.

I need to find The value of x
KiRa [710]

A circle is 360°.

Add the known angle measures and subtract the total from 360°.

115+105+60 =280°

360 - 280 = 80°

X= 80°

How to do number 13 and 14
Murrr4er [49]

From the information: v is 64 while c is 5

Differentiate the new equation h=-16t^{2} + 64t + 5 to get \frac{dh}{dt}= -32t + 64.

no 13). At maximum height this derivative equals zero so: -32t + 64 = 0;  -32t = -64; t=2.Hence ans is 2 secs

no 14). put t as 2 sec in the equation: h=-16t^{2} + 64t + 5.  This gives

h=-16( 2^{2}) + 64(2) + 5; h=-64+128+5=69. Hence h is 69ft
