4 0

Answer:

PR = 7.9

Step-by-step explanation:

By sine rule:

\frac{12.5}{ \sin \: 66 \degree}  =  \frac{PR}{ \sin \: 37 \degree}  \\  \\  \frac{12.5}{ 0.9135454576}  =  \frac{PR}{ 0.6018150232}  \\  \\ PR =  \frac{12 \times 0.6018150232}{0.9135454576} \\  \\ PR =  \frac{12 \times 0.6018150232}{0.9135454576}  \\  \\PR =  \frac{7.22178028}{0.9135454576}  \\  \\ PR = 7.90522269 \\  \\ PR \approx \: 7.9

Solve for n:<br> (n+4)/10 = (n-8)/2
nalin [4]

Answer:

n=11

Step-by-step explanation:

(n+4)/10 = (n-8)/2

We can solve using cross products

(n+4) * 2 = 10 * ( n-8)

Distribute

2n+8 = 10n -80

Subtract 2n from each side

2n+8-2n = 10n-80-2n

8 = 8n-80

Add 80 to each side

8+80= 8n-80+80

88 = 8n

Divide each side by 8

88/8 = 8n/8

11 = n
