A triangle has an area of 63 square inches. if the height s 9 inches. what is the length of the base

14 = b or b = 14

Step-by-step explanation:

Area of a triangle: 1/2*b*h

Area = 1/2*b*h

63 = 1/2*b*9

63 = 9/2b

2(63 = 9/2b)

126 = 9b

/9      /9

14 = b or b = 14

Check:

63 = 1/2*b*9

63 = 1/2*14*9

63 = 7 * 9

63 = 63

Hope this helps!

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
