Which of the pairs of angles are vertical angles and thus congruent?
O <A and <G
O <A and <B
O <C and <F
O <D and <H

the equation is not included but the answer is (1.50, 2.00, 2.75)

step-by-step explanation:

1) the property is   ixi = a ⇔x = a   o x = -a

4(x-5)+3= 15⇒4x-20+3 = 15⇒4x-17= 15⇒4x = 15+17⇒4x = 32⇒x =32/4= 8

4(x-5) +3= -15⇒4x-20 +3 = -15⇒4x-17= -15⇒4x =-15+17⇒4x = 2⇒x =2/4= 1/2

the values are x =8 and x = 0,5

y-y1=m(x-x1)

y-1=1(x-8)
