the vertices of angle PQR are P(3,0),Q(9,-2) and R(9,8)find the area of angle PQR to one decimal place and state the type of triangle

2/8 of 15
sketch it first
length QR = 10 NOTE - perpendicular to x axis so altitude along x axis
altitude from P to QR is along x axis and of length 9-3 = 6
so
area = (1/2)(6)(10) = 30
