If your school is 30 feet tall and 1 feet is 1.26 cm, you would multiply 30 and 1.26 to get the height of the scale model which is 37.8 cm. Then, if each toothpick is 6.3 cm, you would take 37.8 and divide it by 6.3 to get the number of toothpicks you need to build the school, which is 6.
The model will be 6 toothpicks tall.

∠BDC=30, so ∠CBD + ∠BCD=180-30=150
ΔDBC is isosceles, so ∠CBD=∠BCD=half of 150=75
∠ABC=∠ABD-∠CBD=155-75=80
ΔABC is isosceles, so ∠ABC=∠ACB=80
∠BAC=180-80-80=20
