Answer:
127
Step-by-step explanation:
The angles add up to 180° since they are on a straight line. Find 3x - 5.
3x - 5 + x + 1 = 180
4x - 4 = 180
4x = 180 - 4
= 176
x = 176 ÷ 4
x = 44
3x - 5 = 3(44) - 5
= 132 - 5
= 127
Round off the decimals to a sensible number.
So 3.7 would be 4 and 10.2 would be 10.
In this case, it would be (2 × 4 + 8) × 10 which is 160.
The hourly rate is 60, so multiply 60 by the number of hours (h) and add the fee:
Answer: 60h + 35
AOB = 2 . x
2x = 60°
x = 30°
