PLEASE EXPLAIN BECAUSE A GIRL IS COMPLETELY LOST HERE

Don't be lost. First the triangle angles add to 180 degrees so the angle opposite b, call it B, is


B = 180 - 82 - 55 = 43 degrees


We also have a=8 cm and A=55 degrees


By the Law of Sines


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


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


b = \dfrac{ 8 \sin 43 }{\sin 55 } \approx 6.7 \textrm{ cm}

Hello!


To find the value of b, we need to use the Law of Sines. The law states,

sin A / a = sin B / b = sin C / c.


We are given these values: sin A = 55 degrees, side a = 8 cm, sin C = 82 degrees.


Since angle B is not given, we have to find it ourselves. We can find the measure of angle B by subtracting both the given angle values from 180 degrees because every triangle is equal to 180 degrees.


180 - 55 - 82 = 43 | The measure of sin B = 43 degrees.


sin (55) / 8 = sin (43) / b (multiply both sides by b)

0.10239... · b = 0.68199... (divide both sides by 0.10239...)

c = 6.6607...


The measure of side b is equal to about 6.7 centimeters.

Two construction workers, Tyrone and Diego, are standing 15 yards apart, looking up at a piano hanging between the two men from
Yanka [14]

Answer:

The distance between Tyrone and the piano is 23.7 yards

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find the measure of angle P

Remember that the sum of the internal angles of a triangle must be equal to 180 degrees

∠T+∠D+∠P=180°

substitute the given values

65°+77°+∠P=180°

142°+∠P=180°

∠P=180°-142°=38°

step 2

applying the law of sines

\frac{TD}{sin(P)}=\frac{TP}{sin(D)}

substitute the given values

\frac{15}{sin(38\°)}=\frac{TP}{sin(77\°)}

TP=\frac{15}{sin(38\°)}(sin(77\°))\\\\TP=23.7\ yd

therefore

The distance between Tyrone and the piano is 23.7 yards

Tom buys a shirt for 22.00 plus 7% sales tax. His cousin buys a shirt for 18.00 plus sales tax. How much do tom and his cousin p
Novay_Z [31]
Hey You!

Tom:

22*7% = 1.54

His Cousin:

18*7% = 1.26


22 + 1.54 = 23.54

18 + 1.26 = 19.26

So, Tom pays $23.54 and His Cousin pays $19.26 and Tom payed more tax.
