What is the angle of c (∠c)<br><br> 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.

<u>If we interpret our problem in algebriac form, we can say that:</u>

65° + 65° + m∠C = 180°

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

130° + m∠C = 180°

<u>Then, subtract 130° on both sides to isolate our variable.</u>

m∠C = 50°

<u>Now we can safely say that the measure of angle C is 50°.</u>

F(x) = { -2x -1, x ≤ 2
Degger [83]

Answer:

Use the appropriate entry method for piecewise functions for the graphing calculator of interest.

Step-by-step explanation:

For Desmos, the entry looks like ...

f(x) = {x ≤ 2: -2x-1,-x+4}

_____

For a TI-84 calculator, the entry may look like ...

Y₁ = (-2X–1)(X≤2) + (-X+4)(X>2)

The symbols ≤ and > come from the TEST menu, which is the (2nd) shift of the MATH key.

Note that the function is the sum of the pieces, each piece multiplied by a test. For something like 0≤x<2, the multiplier would be a pair of tests:

... (0≤X)(X<2)
