Since the triangles are congruent then corresponding angles and corresponding sides are equal
∠B = ∠Q, hence
6x - 16 = 5x + 2 ( subtract 5x from both sides )
x - 16 = 2 ( add 16 to both sides )
x = 18, hence
∠B = (5 × 18 ) + 2 = 90 + 2 = 92°

Similarly PR = AC
9x - 4 = 6x + 2 ( subtract 6x from both sides )
3x - 4 = 2 ( add 2 to both sides and divide by 3 )
3x = 6 ⇒ x = 2
PR = (9 × 2 ) - 4 = 18 - 4 = 14 cm
Answer:
maybe there's a typo, that dot usually represents the multiplication, and I got 5.52
ok so the answer is A well i think it is at least this one is hard and im sorry if i got it wrong bc i did the math in my head.lol
The total distance of the street is the number of times the wheel turns multiplied by its circumference. Thus:
C = πD
L = nπD
L = 26 x 3.14 x 3.2
L = 261.2 ft
