-12y = -17x - 36

divide through by -12:-#y = -17/-12 x + 3
slope = 17/12

Use the Law of Sines to find the missing angle of the triangle.

Natasha2012 [34]

Answer:

m∠B = 70.0° (nearest tenth)

Step-by-step explanation:

<u>Sine Rule for Angles</u>

$\sf \dfrac{\sin A}{a}=\dfrac{\sin B}{b}=\dfrac{\sin C}{c}$

(where A, B and C are the angles and a, b and c are the sides opposite the angles)

Given:

a = 13
c = 19
A = 40°

Substituting the given values into the formula to find m∠C:

$\implies \sf \dfrac{\sin 40^{\circ}}{13}=\dfrac{\sin C}{19}$

$\implies \sf \sin C=\dfrac{19\sin 40^{\circ}}{13}$

$\implies \sf C=\sin^{-1}\left(\dfrac{19\sin 40^{\circ}}{13}\right)$

$\implies \sf m \angle C=69.96086904^{\circ}$

Interior angles of a triangle sum to 180°

$\implies \sf m \angle A+ m \angle B+m \angle C=180^{\circ}$

$\implies \sf 40^{\circ} + m \angle B+69.960...^{\circ}=180^{\circ}$

$\implies \sf m \angle B=70.03913...^{\circ}$

Therefore, m∠B = 70.0° (nearest tenth)

MAHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH

Natali [406]

I believe it is neither

For one if you plug in either of them the first one is going to be negative 3. But if you use the second one then your answer would be -3+12= -10 but -3+12 is 9 so I would go with neither because I don't see how it's both

A telemarketer sells subscriptions for magazines and receives a commission of 20 % on his sales. How much would his commission b

erastovalidia [21]

The commission of telemarketer will be $75.

Step-by-step explanation:

Given,

Worth of subscription sales = $375

Commission rate = 20%

Amount of commission = 20% of worth of subscription sales

Amount of commission = $\frac{20}{100}*375$

Amount of commission = $0.2*375$

Amount of commission = $75

The commission of telemarketer will be $75.
