Answer:
tan 30 = x / 15
General Formulas and Concepts:
<u>Trigonometry</u>
- [Right Triangles Only] SOHCAHTOA
- [Right Triangles Only] tanθ = opposite over adjacent
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
Angle θ = 30°
Opposite Leg = <em>x</em>
Adjacent Leg = 15
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute in variables [tangent]: tan 30 = x / 15
Answer:
y= 6x -8
Step-by-step explanation:
<u>Slope-intercept form: </u>
y= mx +c, where m is the gradient and c is the y-intercept.

Gradient

= 6
y= 6x +c
To find the value of c, substitute the equation with a pair of coordinates.
When x= 1, y= -2,
-2= 6(1) +c
c= -2 -6 <em>(</em><em>-6</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>
c= -8
Thus, the equation of the line is y= 6x -8.
Answer:
30
24 : 28 would equal 6 : 7
x 65 = 30
Use the proportion of the bracelets
Step-by-step explanation:
-35 x - 625 = 21875 so positive
263 x 0 = 0 so zero
-21 x 451 = - 9471 so negative
-350 x 89 = - 31150 so negative
