Answer:
20.48
The parentheses just means multiplication.
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
Answer:
94 or 95
Step-by-step explanation:
91 + 95 + 87 + 83 = 356
356/4 =89
average so far is 89
356 + 94 = 450
450/5 = 90
356 + 95 = 451
451/5= 90.2
