Answer: A
Step-by-step explanation: Range is the distance between one point to the next. That would make A the correct answer.
A raiz de -9 = a +-3
ou seja 5+3=8
5-3=2
Answer:
x = 35
C = 18.92
A = 71.07
Step-by-step explanation:
x)
Use the Pythagorean theorem to find the unknown side.

For Angle C
The angle C can be found using the inverse sine function.
C=arcsin(opp/hyp)
C=arcsin(12/37)
C=18.92
For Angle A
The sum of all the angles in a triangle is 180 degrees.
A + 90 + 18.92 = 180
A = 71.07
Answer: B) 6
Explanation:
Segment BA is half as long as ZY, since BA is a midsegment.
This means ZY is twice as long as BA
ZY = 2*BA
2*BA = ZY
2*(x-1) = 10
2x-2 = 10
2x = 10+2
2x = 12
x = 12/2
x = 6
Note how this leads to BA = x-1 = 6-1 = 5, which is half as long as ZY = 10.
