Answer:
"between 30 yards and 150 yards"
Step-by-step explanation:
Let one side of a triangle be x and another side be y. To find the possible lengths of the third side, it is given by:
<u><em>Possible length of 3rd side would be between "x - y" and "x + y"</em></u>
<u><em /></u>
Here, given x = 90 and y = 60, so the possible length of 3rd side would be:
90 - 60 = 30,
90 + 60 = 150
Hence, in between 30 and 150
Answer:
The sixth number in series is 13.
Step-by-step explanation:
Given series : 3, -6, 12, 4, 20, ?
The pattern followed by the series is:
The first number = 3
Second number = 3 - 9 = - 6
Third number = - 6 + (9 ×2) = -6 + 18 = 12
Fourth number = 12 - 8 = 4
Fifth number = 4 + (8 ×2) = 20
Sixth number = 20 - 7 = 13
Seventh number = 13 + (7 ×2) = 13 + 14 = 27 and so on.
So as per the above pattern, the sixth number in the series is 13.

Answer:
y =
x - 1
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
y = -
x - 3 is in this form
with slope m = - 
the slope of a perpendicular line is the negative reciprocal of m, hence
= 
(0 , - 1 ) is the y-intercept ⇒ c = - 1
y =
x - 1 ← equation of perpendicular line
