TWO QUESTIONS BELOW: 1) If m<3 is 110 degrees find m<2.
2) If m<4 is 65 degrees, find m<1.

Measure angle 2 is 70 degrees (question 1)

Measure angle 1 is 115 degrees (question 2)

Step-by-step explanation:

assume the other 2 angles sum up to 180 degrees

Subtract measure angle 3 by 180 degrees to find measure angle 2

Hope this helped :) comment if you need more help or clarification

i can't see the picture : /

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
