Answer:
i dont know
Step-by-step explanation:
M∠ADB + m∠BDC = m∠ADC <span>
x + x + 10 = 60
2x + 10 = 60
2x = 60 - 10
2x = 50
x = 50/2
x = 25
a
m</span>∠ADB = x = 25°
b
m∠BDC = x + 10 = 25 + 10 = 35°

Angle Addition Postulate
There are 380 students at Rock-Ledge Middle School.
To figure it out, you have to start by figuring out the total amount of students in band. If 38 = 25% then 38 x 3 = 75% so 114 = 75%. That means there are 152 students in band. That means 40% of the students are in band. Because 20s are easier to work with, you can transfer the 40% to 20% which equals 76. If 76 = 20% then 76 x 4 = 100% so the total number of students is 380!
