Help me understand how to do this

We know that the two angles are congruent (equal in measure), so we take the written out descriptions of the angles and convert them to equations that we set equal to each other.

"Three more than twice a number" = 2x + 3

"54.5 less than three times the number" = 3x - 54.5

2x + 3 = 3x - 54.5

Add 54.5 to both sides

2x + 57.5 = 3x

Subtract 2x from both sides

57.5 = x

Now we plug in 57.5 in the original equations to get the measure of each angle.

2(57.5) + 3 = 118 degrees

3(57.5) - 54.5 = 118 degrees

As we already knew, the angles are congruent.

P.S.: Nowhere in the prompt does it say anything about a triangle, just that we have a pair of congruent angles. Be sure to read each prompt carefully.

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720
