The points (-10, 0) and (-5, 3) fall on a particular line. What is it’s equation in slope-intercept form?
yaroslaw [1]

Answer:

  y = 3/5x + 6

Step-by-step explanation:

When given two points, it is convenient to start with the 2-point form of the equation of a line, then rearrange it to the form needed for the problem. For points (x1, y1) and (x2, y2), the equation is ...

  y = (y2 -y1)/(x2 -x1)·(x -x1) +y1

Filling in the given point coordinates, this is ...

  y = (3 -0)/(-5 -(-10))·(x -(-10)) + 0

  y = 3/5(x +10)

  y = (3/5)x + 6

What’s measure of angle C?
Oduvanchick [21]
The angle is 60° because
B is a right angle and that adds to 90°, so dividing 90 by 3 would get 30

30 x 2 = 60

and to check the answer

x = 30

A=30
B=90
C=60

this adds to 180 which is correct because the angles in a triangle add to 180° :)

Find value of x and y
marshall27 [118]

Answer:

x = 17\sqrt{3}, y = 34

Step-by-step explanation:

Since the triangle is right use trig ratios to find x and y

note exact values sin30° = \frac{1}{2}, tan30° = \frac{1}{\sqrt{3} }

sin30° = \frac{opposite}{hypotenuse} = \frac{17}{y}

multiply both sides by y

y sin30° = 17 ( divide both sides by sin30° )

y = \frac{17}{\frac{1}{2} } = 34

tan30° = \frac{opposite}{adjacent} = \frac{17}{x}

multiply both sides by x

x tan30° = 17 ( divide both sides by tan30° )

x = \frac{17}{\frac{1}{\sqrt{3} } } = 17\sqrt{3}
