What’s the answer ? ?

Because this triangle is an isosceles, we know that angle M and angle L are equal (as shown by the diagram)

So, we make the two values equal

5y-19=56

Take 19 to the other side as a positive

5y=75

y is equal to 15

But, we aren't done yet as the question asks us to find the value of k

So, we do

5*15-19+56+K=180

112+K=180

Take 112 to the other side as a negative number

180-112 is 68

So, angle K is equal to 68 degrees

Ireally don’t understand your problem do you have a better picture of it

so the perpendicular line goes through the given pointyou would get a perpendicular line at some random location

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
