Answer:

e = 9

Step-by-step explanation:

5(e + 6) = 75

Divide each side by 5

5/5(e + 6) = 75/5

e+6 = 15

Subtract 6 from each side

e+6-6 = 15-6

e = 9

Divide both sides by 5

e+6=15

Subtract 6

e=9

From Kansas City to Denver is twice as far as from Kansas City to St. Louis the two distance together total 900 miles what are t

BARSIC [14]

Answer:

KC to StL = 300

KC to Den = 600

Step-by-step explanation:

KC to StL was the base distance, so we'll call that x.

KC to Denver is twice as long, so we'll call that 2x.

If we add the together is is 900 miles total.

x + 2x = 900 Combine like terms

3x = 900 Divide by 3

x = 300

If x is 300, then 2x is 600.

Find the number of distinct triangles with the measurements a = 8, b = 14, and A = 30°.

Maslowich

Answer: 2

Step-by-step explanation:

By the law of sines,

$\frac{\sin B}{b}=\frac{\sin A}{a} \\ \\ \frac{\sin B}{14}=\frac{\sin 30^{\circ}}{8} \\ \\ \frac{\sin B}{14}=\frac{1}{16} \\ \\ \sin B=\frac{14}{16} \\ \\ B=\sin^{-1} \left(\frac{14}{16} \right), 180^{\circ}-\sin^{-1} \left(\frac{14}{16} \right) \\ \\ B \approx 61.04^{\circ}, 118.96^{\circ}$
