209/2 is 104.5, add 0.5 to once and take away 0,5 once so your left with 104 and 105 then 104+105=209 and they’re integers which are consecutive. :))
Angle b and q should equal 10 degrees, because if the triangles are congruent then the angles must be too. So you have to put the equations equal to each other and solve for v. v will equal 2, so you have to plug it back into the equation. The answer for both equations will be 10, meaning that is the measurement of their angles.
Answer:
12 yards
Step-by-step explanation:
side b = √(diagonal^2 - side a^2)
Solve for x

18+13.5+9 = 40.5
Therefore, the perimeter of ΔPQR = 40.5inches
