Answer:
It's 31.5
Step-by-step explanation: The formula for right triangle is A=ab/2. A=area, a is one of the legs and b is the other leg. So you had for one leg 9 and for the other 7. You multiple 9 x 7 = 63. 63/2 = 31.5 for the area
I think the solution is (p,q)=(-2,-5)
b
Step-by-step explanation:
centroid
x=(x1+x2+x3)/3=(0+3+0)/3=3/3=1
y=(y1+y2+y3)/3=(0+0-3)/3=-3/3=-1
centroid =(1,-1)
height: 16 inch
length of base: 10 inch
width of base: 50 feet
128*(1/8)=16 inch
80*(1/8)=10 inch
x*1/8=6.25
x=6.25*8=50 feet
