To see if your answer is correct just <u>add 123.60 and 87.40 together</u>.
Answer:
x = 9 cm
create proportional equation:
1/3(a + b) = 60
a + b = 60 * 3 = 180
1/4(a - b) = 28
a - b = 28 * 4 = 112
a + b = 180
a - b = 112
---------------add
2a = 292
a = 292/2
a = 146
a + b = 180
146 + b = 180
b = 180 - 146
b = 34
so ur 2 angles are : 146 and 34
