X=4 because first u distruste and add the numbers then add 33 to both side
Answer:
1.15
Step-by-step explanation:
tan θ=−4/7, and 270°<θ<360°
θ is in 4th quadrant
sec θ = 8.06 / 7 = 1.15
Answer:
the forth answer
Step-by-step explanation:
Answer:
--- Slope intercept
--- Point slope
Step-by-step explanation:
Given
Perpendicular to
Required
Determine its equation
The general form of an equation is:
Where
By comparison:
Next, we calculate the slope of L.
Because L is perpendicular to , the relationship between their slopes is:
Substitute 4 for m
The equation of L in slope intercept form is:
Substitute -1/4 for m
In point slope form, we have:
Substitute -1/4 for m
THe first thing we need to do is find the hypotenuse. From the tangent we know that the legs of the right triangle are 3 and 4. So this 2/3 of a special right triangle (3-4-5). Thus the hypotenuse is 5. The sin is defined as
. We know the opposite is 4 and hypotenuse is 5. Thus the sin is
