Answer:

74º

Step-by-step explanation:

Ray TV bisects ∠RTS, so ∠RTV=∠STV=(16x-6)º
We also know that ∠RTS=(26x+18)º
So, (16x-6)º+(16x-6)º=(26x+18)º
We don't need parenthesis, 16x-6+16x-6=26x+18
Combine like terms, 32x-12=26x+18
Add, 32x=26x+30
Subtract, 6x=30
Divide, x=5
∠RTV now is [16(5)-6]º=(80-6)º=74º

The speed of a stream is 2 mph. A boat travels 20 miles upstream in the same time it takes to travel 40 miles downstream. What i

nataly862011 [7]

Answer:

The speed of a boat in still water is 6 miles per hour.

Step-by-step explanation:

t = $\frac{20}{s-2}$ (upstream)

t = $\frac{40}{s+2}$ (downstream)

$\frac{20}{s-2}$ = $\frac{40}{s+2}$

40 ( s - 2 ) = 20 ( s + 2 )

40s - 80 = 20s + 40

20s = 120

s = 6 mi / h

The speed of a boat in still water is 6 miles per hour.
