GEOMETRY HELP ME

Find the measures of all the angles listed and if the lines are parallel explain why?

Answers

Answer:

x= 110°

Step-by-step explanation:

if you continue drawing the top purple line you will have a triangle with three angles

70° ; is given

180-140= 40°; is the same angle as the supplement angle of 140° (complementary angles are congruent)

180-70-40 = 70°; because sum of angles in a triangle is 180°

So angle x= 180 -70 = 110 because are a linear pair

Answer:

110 deg

Step-by-step explanation:

The supplement of the 140 deg angle measures 40 deg.

Draw a line through the vertex where angle x is that is parallel to the other two lines. That line splits angle x into two angles, an upper angle and a lower angle.

By alternate interior angles, the lower angle that is part of angle x measures 70 deg. Also by alternate interior angles, the upper angle that is part of angle x measures 40 deg.

x = 70 + 40 = 110

Answer: 110 deg

Write an equation for the line in slope-intercept
form.
(Use integers or fractions for any numbers in the
equation.)

Answers

The equation would be: y=3x+5
The line crosses the y-axis at 5, so that’s the y-intercept.
The slope is 3 because it goes up by 3 and then 1 to the right, as a fraction it’s 3/1 which is just 3
