Answer:
Answer = 140
Step-by-step explanation:
360 = 9x + 14x + 4x + 90
360 - 90 = 27x
270 = 27x
x = 270 / 27
x = 10
14 x 10 Angle F
Measure of angle F = 140
Answer:
b=-a
Step-by-step explanation:
Becaude when b is <u>positive</u> a will be <u>negative</u>
And when b is <u>negative</u> a will be <u>positive</u>.
Remember that the rule with multiplying exponents with the same base is to add the exponents together.
In this case: 
10^12 is your answer.
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:
