The answer will be A due to them being on opposite sides with the triangle having adjacent measures so both of those angles given provide the same measure
The answer is A, 13. Since we know line DB is a median (the middle), it tells us that line BC must equal line AB. Simply just do 26/2.
Mean is a form of average, and in order to find this we add up all the numbers then divide by the amount of numbers we have.
So, we have 5 numbers here. (8, 17, 9, 3, and 13)
8 + 17 + 9 + 3 + 13 = 50
50/5 = 10
The mean of those five numbers is 10.
Answer:
26 mm
Step-by-step explanation:
A=wl= 42 mm²
l=7, w= 42/7= 6 mm
P=2(l+w)= 2(7+6)= 26 mm
