Answer:
87 degrees
Step-by-step explanation:
The triangle with the angles 79 and 15, we can find the last value because all angles in a triangle add up to 180. So, 180-79-15= 86 degrees for the angle of the triangle.
Because the 86 degree angle is complimentary, or when added up to the adjacent angle, is 90 degrees (we see that little box sign), that means that 90-86=4 degrees for the upper triangle in the angle that isn't the question mark. Now that we know 2 values for the top triangle, we can solve for the third value by subtracting those two from 180.
180-89-4=87 degrees. Hope this helps!

They are two different letters
Answer:
-6
Step-by-step explanation:
The equation 2x-12y=168 is in standard form so in order to dtermine the slope you need to convert it to slope-intercept form.
1. subtract 2x from both sides.
-12y=-2x+168
2. divide all terms by -12 (to isolate the y)
y=1/6x-14
3. the equation of a line that is the perpendicular is the opposite and reciprocal of the given slope.
the opposite of 1/6 is -1/6.
The reciprocal of -1/6 is -6/1 OR -6.
-6 is the slope of a line pependicular to 2x-12y=168.
Hope this helps.
