Xelga [282]

Answer:

Given: A = 72°, a = 34, b = 21

Calculated: B = 35.97°, C = 72.03°, c = 34.00

Step-by-step explanation:

$\dfrac{\sin A}{a} = \dfrac{\sin B}{b}$

$\dfrac{\sin 72^\circ}{34} = \dfrac{\sin B}{21}$

$\sin B = \dfrac{21\sin 72^\circ}{34}$

$\sin B = 0.5874$

$B = \sin^{-1} 0.5874$

$B = 35.97^\circ$

C = 180° - 72° - 35.97°

C = 72.03°

$\dfrac{\sin A}{a} = \dfrac{\sin C}{c}$

$\dfrac{\sin 72^\circ}{34} = \dfrac{\sin 72.03^\circ}{c}$

$c = \dfrac{\sin 72.03^\circ \times 34}{\sin 72^\circ}$

$c = 34.00$

Given: A = 72°, a = 34, b = 21

Calculated: B = 35.97°, C = 72.03°, c = 34.00

Will ran four miles on his first day of training. The next day he ran one-third that distance. How far did he ran the second day

goldfiish [28.3K]

12 miles. You need to multiply the reciprocal of 1/3 which is 3. So you multiply 4 miles, what he ran on the first day and 3 which makes the answer 12 miles.
