point a is the center of this circle.
the ratio of the lengths of (ef/bc) and (ad/ih) is 2: 1.
step-by-step explanation:
1) the property is ixi = a โx = a o x = -a
4(x-5)+3= 15โ4x-20+3 = 15โ4x-17= 15โ4x = 15+17โ4x = 32โx =32/4= 8
4(x-5) +3= -15โ4x-20 +3 = -15โ4x-17= -15โ4x =-15+17โ4x = 2โx =2/4= 1/2
the values are x =8 and x = 0,5
