Answer: These are all the sides and angles:
a = 3
b = 18.76
c = 19
A = 9.1°
B = 80.9°
C = 90°
Explanation:
As per the usual convention the side c is opposite to the angle C, side a is opposite to angle a, and side b is opposite to angle B.
That means that c is the hypotenuse of the triangle.
Then, a is one leg, and b is the other leg.
Therefore, you can use Pythagorean theorem to find the unknown leg, b:
c² = a² + b² ⇒ b² = c² - a²
⇒ b² = 19² - 3² = 352
⇒ b = √352 = 18.76
Now you can use any trigonometric ratio to find one of the unknowm angles.
I wll use sine ratio to find the angle opposite to a:
sin (A) = a / 19 = 3 / 19
⇒ A = arcsin (3/19) ≈ 9.1°.
Then, the other angle is: B = 180° - 9.1° - 90° = 80.9°
And those are all the sides and angles:
a = 3
b = 18.76
c = 19
A = 9.1°
B = 80.9°
C = 90°
Answer:
Piyush walks faster than Laura
Step-by-step explanation:
we know that
The rate or speed is equal to the slope of the linear equation
<em>Laura</em>
y=3.5x
The slope is 
<em>Piyush</em>
Determine the slope of the line
we have the points
(0,0) and (4,18)
The line represent a direct variation (because passes through the origin)
so
For x=4 h, y=18 mi
substitute
Compare the slopes
therefore
Piyush walks faster than Laura
Answer:
The 2 pound bag of gummy bears
Step-by-step explanation:
You do 1.5/4.35 which = 2.9 the 2.9 is $2.90 per pound
Then, you do 5.3/2 which = 2.6 this 2.6 is $2.60 per pound
$2.60 < $2.90 there for the 2 pound bag of gummy bears is the better deal
