Answer:

  x = 5

Step-by-step explanation:

The given side is opposite the angle, and the unknown is the hypotenuse. The relevant trig relation is ...

  Sin = Opposite/Hypotenuse

  sin(30°) = (5/2)/x

  x = (5/2)/sin(30°) = (5/2)/(1/2) = 5/1

  x = 5

__

<em>Additional comment</em>

In this 30°-60°-90° "special" right triangle, the long leg is √3 times the short leg, so ...

  y = (5/2)√3

Give the slope of y + 2 = 3(x - 7) and a point on the line.
chubhunter [2.5K]

Answer:

The slope --> m = 3

A point from the line --> ( 0 , 23 )

Step-by-step explanation:

To find the slope you put the equation y+2=3(x-7) into Slope-Intercept Form (y=mx+b)

y+2=3(x-7) --> y+2=3x-21 --> y=3x-23

m is the slope and m=3

b is the y-intercept and b is 23

Hope this helps .-.
