Answer:6
Step-by-step explanation:solve the equation, you know that it equals 90 because the angle is 90
so 16x-6=90
+6 both sides
16x=96
divided by 16 both sides to isolate x
x=6
R = = 3.6 and A = 2
given that R is inversely proportional to A, then
R = ← k is the constant of variation
To find k use the condition R = 12 when A = 1.5
k = RA = 12 × 1.5 = 18
the equation is therefore
R =
when A = 5, then
R = = 3.6
when R = 9, then
9 = ( multiply both sides by A )
9A = 18 ( divide both sides by 9 )
A = 2
9.18 because the 1 is in the tenth place and the 6(in the thousandths place) rounds up to make the 7(in the hundredths place) into an 8
