Answer:
A;H;D;G
Step-by-step explanation:
Altitude is a line from a vertex that intersects a side at a 90 degree angle. DE is the only altitude shown
Perpendicular bisectors divide a side into 2 congruent pieces, at a 90 degree angle. GB is the only perpendicular bisector shown.
An angle bisector is a line that divides an angle into 2 angles with the same measure. CF is the only angle bisector shown.
A median is a line that goes through a vertex and divides a side into 2 congruent lengths. AB is the only such example.
Answer:
x = 9, WX = 34
Step-by-step explanation:
Two tangent segments to a circle from the same external point are congruent, that is
WX = YX, substitute values
7x - 29 = 2x + 16 ( subtract 2x from both sides )
5x - 29 = 16 ( add 29 to both sides )
5x = 45 ( divide both sides by 5 )
x = 9
Thus
WX = 7x - 29 = 7(9) - 29 = 63 - 29 = 34
Answer:
6m-27
Step-by-step explanation:
We have to calculate a monthly annuity.
Total = Monthly Amount * [(1 + rate)^(n + 1) -1] / [rate] - Monthly Amount
where "n" is the number of compounding periods per year.
and n = 4.5*12 = 54
rate = rate/n = .055 / 12 =
