Triangle PQR has vertices P(-2,8), Q(2, 4), and R(4,6). Which best describes triangle PQR?

an isosceles triangle with PQ=QR (option C)

Step-by-step explanation:

A. a right tringle with PQ ⊥ QR

Step-by-step explanation:

If you plot the points on a graph you'll notice that the triangle formed is not an isosceles triangle and is in fact a right triangle with PQ being perpendicular to QR.

i think it is 70

step-by-step explanation:

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
