Answer:
Step-by-step explanation:
Given equation of line:
To find the equation of line perpendicular to the line of the given equation and passes through point (8,2).
Applying slope relationship between perpendicular lines.
where 
and 
are slopes of perpendicular lines.
For the given equation in the form 
the slope can be found by comparing 
with standard form.
∴ 
Thus slope of line perpendicular to this line would be given as:
∴ 
The line passes through point (8,2)
Using point slope form:
Where 
and 
So,
Using distribution.
Adding 2 to both sides.
Thus the equation of line in standard form is given by:
Answer:
30
Step-by-step explanation:
130 + 20 = 150
All angles added together in a triangle equal 180 so...
180 - 150 = 30
I hope this helps!
I(interest)=P(princple)R(rate)T(time)
I=420*.07*1=$29.4
A is correct.
Peace.
Answer:
x = 21°
Step-by-step explanation:
Complementary angles have a sum of 90°. If ∠A + ∠B = 90°, we know that
x - 6° + 3x = 90°.
4x - 6° = 90°
4x = 96°
x = 24°
