Answer:
The slope of the line reflects the actual d.
1) Δ ABC
m∠B + m∠C + m∠BAC = 180⁰
2) m∠DAB + m∠BAC = 180⁰ because m∠DAB and m∠BAC are supplementary angles.
3) m∠B + m∠C + m∠BAC = m∠DAB + m∠BAC
m∠B + m∠C = m∠DAB
32⁰ + x = 98⁰
x=98 - 32 = 66 ⁰
Answer: A. 66⁰.
The answer is 345 students.
I did reverse math(i don't remember the name)
138/.4=345
Now check it:
345*.4=138
I hope I helped somehow!
