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°
In order to isolate any term from an equation we need to clear out any different variable or numbers different from the one we want
in this case I is being multiplied by R, so we need to do the opposite which is divide in order to eliminate
But since this is an equality we must do it on both sides so de equation does not get altered
Then we simplify the equation
