A system of equations is shown x-2y=-5 2x+4y=14

Mathematics
1 answer:
gladu [14]2 years ago
7 0

Answer: here you go

Step-by-step explanation:

A) 2x + 4y = 14

B) 4x + y = 20

If you multiply equation A by -2, then when the equations are added, the x will be eliminated.

The solutions are:

X = 4.714285714285714

Y = 1.1428571428571428

What is the trigonometric ratio for sin C?
Vesna [10]
<h3>Answer:  9/41</h3>

==========================================================

Explanation:

We have a triangle with these three sides.

  • a = 80
  • b = unknown
  • c = 82

Use the pythagorean theorem to find b

a^2+b^2 = c^2

b = sqrt(c^2 - a^2)

b = sqrt(82^2 - 80^2)

b = sqrt(324)

b = 18

This is the missing vertical leg of the triangle. And this is also the side opposite angle C.

We have enough information to compute the sine of the angle.

sin(angle) = opposite/hypotenuse

sin(C) = AB/AC

sin(C) = 18/82

sin(C) = (9*2)/(41*2)

sin(C) = 9/41
