Answer:
90 degrees
A right angle is equal to 90 degrees. A line segment (AB) drawn so that it forms right angles with a line (CD).
Step-by-step explanation:
Legnth are x and y
x+y=100
one is 16 more than other
x is 16 more than y
x=16+y
x=16+y therefor we can put 16+y for x
(16+y)+y=100
16+y+y=100
16+2y=100
minus 16 both sides
2y=84
divide by 2
y=42
sub back
x=16+y
x=16+42
x=58
the legnsh are
42 cm and 58cm
Finding the square root of a number is the inverse operation of squaring that number. Remember, the square of a number is thatnumber times itself. The perfect squares are the squares of the wholenumbers. The square root of a number, n, written below is the number that gives n when multiplied by itself.
Answer:
D I'm sure....................... :D
Recall that r^2 = x^2 + y^2, so that r = sqrt(x^2+y^2).
y
r = 3 sin g becomes sqrt(x^2+y^2) = 3*-----------------------
sqrt(x^2+y^2)
Squaring both sides,
9y^2
x^2+y^2 = -----------------
x^2 + y^2
If this is correct (and I'm not convinced that it is), then (x^2+y^2)^2 = 9y^2
shows the relationship between x and y. Can anyone improve on this result?
