Answer:
6
Step-by-step explanation:
Given I varies inversely with R then the equation relating them is
I =
← k is the constant of variation
To find k use the condition R = 12 when I = 3
k = IR = 3 × 12 = 36
I =
← equation of variation
When I = 6, then
6 =
, hence
R =
= 6

Answer:
the angle is 245°
Step-by-step explanation:
that is a pentagon, (a shape with 5 sides)
we know 4 of the angles in the pentagon
the sum of those 4 angles is
58°+100°+112°+25°=295°
to find a shapes total amount of °, the equation is (n-2)x180°
(5-2)x180°
=540°
540°-295°=245°
x=245°
Subtract the sum of the two angles from 180 degrees. The sum of all the angles of a triangle always equals 180 degrees. Write down the difference you found when subtracting the sum of the two angles from 180 degrees.
