The measure of PQR is 75°. The length of radius QR is 4 inches. What is the approximate area of sector PQR? Use 3.14 for a A 20.94 in?
B. 5.24 in
C. 2.62 in?
D
10.47 in?

  q

step-by-step explanation:

each line from a vertex to the midpoint of the opposite side is called a median. the point where the medians intersect, point q, is the centroid.

the centroid of δabc is point q.

step-by-step explanation:

the first 5 right here the next 5 i will upload as separate question

step-by-step explanation:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
