Answer:

y is 70° and x is 40 °

Step-by-step explanation:

the triangle has two equal sides as shown on the diagram...so the next angle to 110° which is 70° is equal to y....then by calculation y + x should give us 110° so if y is 70 then x is 40.

Answer:

y = 70

x = 40

Step-by-step explanation:

The interior angle connected to 110o is the supplement of the 110o angle.

180 - 110 = 70o

The triangle is marked as having 2 equal sides which means that there must be 2 equal angles opposite these 2 sides. Therefore y is also 70o

All triangles have 180o

Therefore x + y + y = 180

We know the ys = 70 each. Substitute into the equation above

x + 70 + 70 = 180                  Combine  

x + 140 = 180                         Subtract 140 from both sides.

x = 180 -  140

x = 40

Which lines are parallel? Why?
Shtirlitz [24]

9514 1404 393

Answer:

  C) c || d by converse of corresponding angles

Step-by-step explanation:

Only corresponding angles where transversal b crosses lines c and d are shown. All answer choices involving a||b or interior angles can be eliminated from consideration.

The "corresponding angle" theorem tells you corresponding angles are congruent if the lines are parallel.

The converse of that theorem tells you the lines are parallel if the corresponding angles are congruent. Here, the angles are shown congruent, so the "converse" theorem applies.

A student says that the x-intercept of the graph of × + 2y =5 is the point (0,5). Is the student correct or incorrect? Explain y
ivanzaharov [21]

The student is incorrect, the actual x-intercept is (5, 0).

<h3>Is the student correct or incorrect?</h3>

Here we have the equation:

x + 2y = 5

The student says that the x-intercept is the point (0, 5).

So if you look at the point you already can see that the student is incorrect, this is because the x-intercept always must have a y-value of 0. (the graph only intercepts the x-axis when y = 0).

So the point (0, 5) can't be an x-intercept.

For the given function:

x +2y = 5

The x-intercept is given by:

x + 2*0 = 5

x = 5

So it is (5 , 0).

Musya8 [376]

Answer:

65 degrees.

Step-by-step explanation:

If LN and OQ are parallel, and QPM is 115, then LMK is also 115. LMP is the supplement, so it would be 65

Hope this helps!
