Answer:
(a) 3.8
Step-by-step explanation:
The Law of Sines can be used to find a missing side length in a triangle where the angles are known and at least one side is given. It tells you the ratio of side lengths is equal to the ratio of the sines of their opposite angles. In effect, longer sides are opposite larger angles.
__
<h3>compare angles</h3>
The given side length (DE=3) is opposite given angle F=50°. The unknown side length EF is opposite larger angle D=75°.
<h3>compare sides</h3>
Since the unknown side is opposite a larger angle than the other angle given, the length of the unknown side will be longer than the side given.
EF > DE
EF > 3
Only one answer choice satisfies this inequality.
EF = 3.8
__
<em>Additional comment</em>
If you want to do the actual computation, we have ...
EF/sin(D) = DE/sin(F)
EF = DE·sin(D)/sin(F) = 3·sin(75°)/sin(50°) ≈ 3.7828
EF ≈ 3.8
Answer:
x =27
Step-by-step explanation:
from Z angls rule the agle (BDE) =72
and total angl on D =180
so, 2x +2x+72=180
4x = 180 -72
4x = 108 (divied both sides by 4)
x= 27
Answer: $35.75
Step-by-step explanation:
1) $25 for the manicure
2) $25*(0.20) = $5 for the tip
3) $5.75 for the tip
$25 + $5 + $5.75 for the total
$35.75 total
Answer:
So let's take a look into the question, "Mrs. Grudman bought a dishwasher at a special sale. The dishwasher regularly sold for
$912. No down payment was required. Mrs. Grudman has to pay $160 for the next six months. What is the average amount she pays in interest each month?"
Step-by-step explanation:
So, " Mrs. Grudman has to pay $160 for the next six months" they want us to multiply, $160
x
6
_______
960
So, 960 is your answer. Hope this helps!
