Answer:
The length of s is 5.1 inches to the nearest tenth of an inch
Step-by-step explanation:
In Δ RST
∵ t is the opposite side to ∠T
∵ r is the opposite side to ∠R
∵ s is the opposite side to ∠S
→ To find s let us use the cosine rule
∴ s² = t² + r² - 2 × t × r × cos∠S
∵ t = 4.1 inches, r = 7.1 inches, and m∠S = 45°
→ Substitute them in the rule above
∴ s² = (4.1)² + (7.1)² - 2 × 4.1 × 7.1 × cos(45°)
∴ s² = 16.81 + 50.41 - 41.1677568
∴ s² = 26.0522432
→ Take √ for both sides
∴ s = 5.10413981
→ Round it to the nearest tenth
∴ s = 5.1 inches
∴ The length of s is 5.1 inches to the nearest tenth of an inch
Answer:
5x-4y+4
Step-by-step explanation:
3x-4y-2+2x+6
Gathers like terms together:
3x+2x= 5x
-4y= -4y
-2+6= 4
Put it together:
5x-4y+4
16 min bucket will drop at 3:36 and 14 min bucket will drop at 3:31
It's 65. Because you add the other angles and get 90+25 and get 115. 180 -115 = 65.
