2x+2x+6x= 180
10x=180
X= 18
Angle C = 36
<u>Answer:</u>
-2/3
<u>Step-by-step explanation:</u>
We are to find the slope of a line which is perpendicular of a line with an equation
.
We know that the slope of line which is perpendicular to another line is the negative reciprocal of that perpendicular line.
So writing the given equation of a line in the slope intercept form:
---> 
Here the slope of this line is
so the slope of a line which is perpendicular to the given line will be
.
Answer:
yes

Answer:

Step-by-step explanation:
In a given triangle, the sum of every angle is always
. Here, we are given a right angle (
), as well as another
angle. Simply subtracting from 180 will give us the answer.
