Answer:

$47.44

Step-by-step explanation:

The sum of hours worked= 3.5hrs + 2.25hrs= 5.75hrs

Money earnt= rate x no. hours= 5.75hrs * $8.25/hr = $47.4375

Round to nearest cent = $47.44

if a and b are acute angles such that sinA=4/5 and cosB=12/13, calculate, without using tables: sin(a-b)
kolbaska11 [484]
\sin \alpha = \frac{4}{5} \\ \cos \alpha  =  \sqrt{1-\sin^2 \alpha }= \sqrt{1- \frac{16}{25} }   = \sqrt{ \frac{9}{25} }= \frac{3}{5} \\    \\ \cos \beta = \frac{12}{13}  \\  \sin \beta  =  \sqrt{1-\cos^2  \beta }= \sqrt{1- \frac{144}{169} }   = \sqrt{ \frac{25}{169} }= \frac{5}{13}


\\  \\ \sin (\alpha- \beta ) =\sin \alpha \cos \beta -\cos \alpha \sin \beta = \frac{4}{5}\times \frac{12}{13}-   \frac{3}{5}\times \frac{5}{13} =  \frac{48}{65}- \frac{15}{65}=  \frac{33}{65}

Answer:
sin(α-β) = 33/65

Given:

In the given triangle the measure of two angles are 102 degree and 28 degrees and the sides of the triangle are a, 27 cm, c.

To find:

The value of a.

Solution:

Let the given triangle be ABC, such that,

m\angle B=28^\circ

m\angle C=102^\circ

b=27\ cm

Using angle sum property of triangles, we get

m\angle A+m\angle B+m\angle C=180^\circ

m\angle A+28^\circ+102^\circ=180^\circ

m\angle A=180^\circ-28^\circ-102^\circ

m\angle A=50^\circ

According to the Law of Sines:

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

\dfrac{\sin 50^\circ }{a}=\dfrac{\sin 28^\circ }{27}

\dfrac{27\times \sin 50^\circ }{\sin 28^\circ}=a

\dfrac{27\times \sin 50^\circ }{\sin 28^\circ}=a

a\approx 44.06

Therefore, the value of a is about 44.06 cm.
