What is the angle of c (∠c) Help immensely I will give brainliest

jeka57 [31]

Answer:

The measure of ∠c is 50°.

Step-by-step explanation:

When it comes to problems like these, there are two types of angles that should be kept in mind: complementary angles and supplementary angles.

Complementary angles are angles that add up to 90° (a right angle). Supplementary angles are angles that add up 180° degrees (a straight angle). A good way to recall this information in layman's terms is to remember this: complements are always right.

So now let's apply what we've learned to the problem. We have a straight angle that is composed of two 65° angles and an unknown C angle. We know that when angles add up to 180°, they're supplementary angles.

If we interpret our problem in algebriac form, we can say that:

65° + 65° + m∠C = 180°

Now we just solve this problem like any other algebriac equation. First, you can combine like terms.

130° + m∠C = 180°

Then, subtract 130° on both sides to isolate our variable.

m∠C = 50°

Now we can safely say that the measure of angle C is 50°.

Find the slope between (8,-2) and (7,-2)

dezoksy [38]

$\text {Slope = } \dfrac{Y_2-Y_1}{X_2 - X_1}$

$\text {Slope = } \dfrac{-2 -(-2) }{8-7} = 0$

Slope = 0 (The graph is a horizontal line that cuts the y at -2)

-------------------------------------------------------
Answer : Slope = 0
-------------------------------------------------------

How would you draw a counterexample to this?

NeX [460]

Melanie said:
Every angle bisector in a triangle bisects the opposite side perpendicularly.

A 'counterexample' would show an angle bisector in a triangle that DOESN'T
bisect the opposite side perpendicularly.

See my attached drawing of a counterexample.

Both of the triangles that Melanie examined have equal sides on both sides
of the angle bisector. That's the only way that the angle bisector can bisect
the opposite side perpendicularly. Melanie didn't examine enough different
triangles.

Can anyone help me with my math homework please

Delvig [45]

125 goes to 5^3, 5^2 goes to (3+2) x 5, and 50 stays the same.
