As of right now it is not likely for him to get a B. This is because his average is 63.6% so unless he gets better scores, he's stuck with an F.
They left with 121$ Bc they was with single ticket
W is 5 units
w=(P-2l)/2
w=(30-2(10))/2
w=(30-20)/2
w=(10)/2
w=10/2
w=5
Well the only thing that would make these triangles not congruent is dilation, Thus, translation, reflection, and rotations all make the triangles congruent.
The bottom one and third one are not congruent while everything else is.
