Answer:

60,120

Step-by-step explanation:

$a = 4x + 12 \\ b = 2(4x + 12) \\( 4x + 12) + 2(4x + 12) = 180 \\ 4x + 12 = 180 \div 3 \\ 4x = 48 \\ x = 12 \\ \\ a = 60 \\ b = 120$

The measure of one angle is twelve more than four times a number.﻿ The measure of a second angle is twice as large as the first,
