∠1 and ∠2 are complementary angles. The measure of ∠1 is 42°. The measure of ∠2 is (3x)°. Find the value of x.

I hate when the algebra pretends to be geometry.

∠2 = 90 - 42 = 48 degrees

3x degrees = 48 degrees

3x = 48

x = 16

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value
