1 answer:

7 0

5y = 20x - 30
5 5
y = 4x - 6
5(4x - 6) = 20x - 30
5(4x) - 5(6) = 20x - 30
20x - 30 = 20x - 30
 +30 +30 
 20x = 20x
 20 20
 x = 1
 5y = 20(1) - 30
 5y = 20 - 30
 5y = -10
 5 5
 y = -2
 5(-2) = 20(1) - 30
 -10 = 20 - 30
 -10 = -10
 (x, y) = (1, -2)

What is the value of r? Round your final answer to the nearest whole number.

vaieri [72.5K]

Answer:

r = 13

Step-by-step explanation:

Hypotenuse is the side opposite to 90 degree angle, so hypotenuse is r.

Also, with respect to the angle given, the side "12" is the opposite.

So we have opposite side to angle and we need hypotenuse. Which trigonometric ratio related opposite with hypotenuse? It is SINE.

So we can write:

$Sin(67.4)=\frac{Opposite}{Hypotenuse}=\frac{12}{r}\\rSin(67.4)=12\\r=\frac{12}{Sin(67.4)}\\r=12.99$

Rounded to nearest whole number, r = 13
