Answer:
14°
Step-by-step explanation:
To find m∠D, the value of x must be known. Because ∠C and ∠D are vertical angles, we can use the equation -x + 26=2x - 10 to find the value of x. After solving the equation, we find that x = 12, so by plugging in the value of x into the original expression, it is shown that m∠D = 14°.

Answer:

Step-by-step explanation:
The initial line is given in "point-slope form" (
therefore we can easily extract from it the slope, and obtain from it what should be the slope of a line perpendicular to it:
Given the expression: 
we understand that the slope is "-2", and the point through which the line passes is the point (6,4) on the plane. We are concerned about the slope, since a line perpendicular to the given line must have a slope that corresponds to the "opposite of the reciprocal" of the original slope.
The opposite of "-2" is "2", and the reciprocal of this is "1/2".
Therefore the slope of the perpendicular line must be "1/2".
Now we can build the equation of the line perpendicular line through the point (-2,-2) by using again the "point-slope form":

Solving for y in this last expression we express the line in slope_y-intercept form:
Answer:
C
Step-by-step explanation:
we are just multiplying 6.1x0.12 it gives us 0.732 simple
