Answer:
1.5
Step-by-step explanation:
225° bisects Q III
315° bisects Q IV
-270° = 90°
405° = 45° bisects Q I
cos(225) sin(315) + sin( –270) tan(405) = ?
(-½√2)(-½√2) + 1(1) = ?
0.5 + 1 = 1.5

Answer:
Here u go
Step-by-step explanation:
1. 40/100 × 129.50 = 51.80
2. 129.50 - 51.80 = 77.70
3. 15/100 × 77.70 = 11.66
4. 77.70 + 11.66 = 66.04
