Find the measure of angle x in the figure below:A:35
B:48
C:69
D:78
Find the measure of angle x in the figure below: - 1

Answers

Answer 1
Answer: The best way to solve for x is to first solve for y and then subtract values. The top of "line" of the 3 angles togethers add up to 180 degrees. So from this, you can deduct this equation into 52+59+y=180. To solve for y, subtract 52 and 59 from the left hand side and rights hand side of the equation. now you know the value is y=180-52-59=69. So the value of y is 69 degrees. 
Now you know two angles of a triangle and the sum of the angles in a triangle is 180 degrees. So the equation is x+69+63=180. To solve for x, subtract 69+63 from both sides. x=180-69-63=48. So you know that x=48 degrees.

Write and equation in standard form for a line that is (a) parallel (b) perpendicular to the line with an equation of y= 3x - 5 that passes through the point (5,8)

Answers

Answer:

  (a) 3x -y = 7

  (b) x +3y = 29

Step-by-step explanation:

(a) The standard form of the given line is ...

  3x -y = 5

The parallel line will have a constant on the right that makes it go through (5, 8), so it will be ...

  3x -y = 3(5) -(8)

  3x -y = 7

__

(b) The perpendicular line will have coefficients for x and y swapped and one of them negated. Again, the constant is chosen to make it go through (5, 8).

  x + 3y = (5) +3(8)

  x + 3y = 29

Jay graphed the line y = x-6 on a coordinate plane. He drew an image of the line 3 units to the right of the original line. What is the same about the two lines?

Answers

The lines are parallel, because they have the same gradient but are just in different positions ie. y = x-9.

Answer:

No, he is not correct. Jay drew a line through the origin, but the line did not connect all three points. Not all the points lie on the line, which is necessary for a proportional relationship.

Step-by-step explanation:

It's the sample response.

So basically, you want to show why the two lines (m and n ) are the "same". To show this you would say <4 &<5 are also supplementary because it is the same as <3 & <6. I think this is what the question is asking. To prove this you use the Converse Theorem. Which is what I just showed you with the angles.
