The difference of two complementary angles is 17 degrees. find the measures of the angles

ryzh [129]

Answer:

The angle measures are 53.5° and 36.5°.

Step-by-step explanation:

We can create a systems of equations, assuming x and y are the angle measures.

Since the two angles are complementary, their angle measures will add up to 90.

x + y = 90

x - y = 17

We can now use the process of elimination, and end up with:

2x = 107

Dividing both sides by two gets us

x = 53.5

Substituting this value into an equation will get us y

53.5 + y = 90

y = 36.5

Hope this helped!

find the point-slope equation of the line perpendicular to the line y=2x+5 passing through the point (1,4). (please include solu

pishuonlain [190]

First off, let's keep in mind that perpendicular lines have negative reciprocal slopes, hmmm so what's the slope of y = 2x + 5?

well, notice, that equation is in slope-intercept form, thus $\bf y=\stackrel{slope}{2}x+5$ .

$\bf \stackrel{\textit{perpendicular lines have \underline{negative reciprocal} slopes}}
{2\implies \stackrel{slope}{\cfrac{2}{1}}\qquad \qquad \qquad \stackrel{reciprocal}{\cfrac{1}{2}}\qquad \stackrel{negative~reciprocal}{-\cfrac{1}{2}}}$

so, we're really looking for the equation of a line whose slope is -1/2 and runs through 1,4.

$\bf (\stackrel{x_1}{1}~,~\stackrel{y_1}{4})\qquad \qquad \qquad 
slope = m\implies -\cfrac{1}{2}
\\\\\\
% point-slope intercept
\stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-4=-\cfrac{1}{2}(x-1)$
