Answer:

The answer to your question is x = 40°

Step-by-step explanation:

According to the picture we determine that the triangle to the right is  isosceles so two of its angles are equal.

Remember that the sum of the internal angles in a triangle equals 180°

                            2x° + 100° = 180

- Subtract 100 in both sides

                            2x + 100 - 100 = 180 - 100

- Simplify

                            2x = 80

-Divide both sides by 2

                            2/2 x = 80/2

Simplify and result

                                  x = 40°

25 POINTS PLEASE HELP ME!! Sam conjectures that for x ≤ - 2, it is true that x^5 + 7 > x^3. Is Sam’s conjecture correct? Why
CaHeK987 [17]

The true statement about Sam’s conjecture is that the conjecture is not correct

<h3>How to determine if Sam’s conjecture is correct or not?</h3>

Sam’s conjecture is given as:

For x ≤ - 2

It is true that x^5 + 7 > x^3.

The inequality x ≤ - 2 means that the highest value of x is -2

Assume the value of x is -2, then we have:

(-2)^5 + 7 > (-2)^3

Evaluate the exponents

-32 + 7 > -8

Evaluate the sum

-25 > -8

The above inequality is false because -8 is greater than -25 i.e. -8 > -25 or -25 < -8

Hence, the true statement about Sam’s conjecture is that the conjecture is not correct
