Step-by-step explanation:
36A) AB = 4/ sin 30° = 4/ 0.5 = 8 cm
36B) AC = 4/ tan 30° = 4/ 0.577 = 6.9 cm
36C) BD = 4/sin 45° = 4/ 0.707 = 5.7 cm
36D) area of ∆ABC = ½×6.9×4= 13.8 cm²
36E) sin A = sin 30° = 0.5

Answer:
Step-by-step explanation:
<u>The Sum:</u>
- 3x²y - 5a + 4b + (-9x²y - 7b + 4a) =
- 3x²y - 9x²y - 5a + 4a + 4b - 7b =
- -6x²y - a - 3b
<u>The difference:</u>
- 3x²y - 5a + 4b - (-9x²y - 7b + 4a) =
- 3x²y + 9x²y - 5a - 4a + 4b + 7b =
- 12x²y - 9a + 11b
<u>Subtract the sum from the difference:</u>
- 12x²y - 9a + 11b - (-6x²y - a - 3b) =
- 12x²y + 6x²y - 9a + a + 11b + 3b =
- 18x²y - 8a + 14b
