Answer:
c+13>78
the inequality sign is > and not ≥ because they have to break the record; they can't get the same number
Answer:
First we need to calculate ∠R
Since ∠R is one of three angles of ΔRDJ, we have:
∠R + ∠D + ∠J = 180°
∠R = 180° - ∠D - ∠J
∠R = 180° - 83° - 39° = 58°
Since ΔRDJ ~ ΔTRB, we can con conclude that:
∠R = ∠T
Because ∠R = 58°
=> ∠T = 58°
