Is this always sometimes or never true.If a triangle has two acute angles it must be an acute triangle

2 answers:

A triangle has an interior angle total of 180 degrees, and if any of those three angles are obtuse, that forms an obtuse triangle.

Now suppose we had a triangle with two acute angles, but not having those two angles add up to more than 90 (consider 30 degrees and 20 degrees).

We can find the unknown angle through some quick subtraction (180 - 30 - 20 = 130).

Since one of the angles is an obtuse angle, this triangle is an obtuse triangle, even though this triangle possesses two acute angles (try drawing a picture, it'll help you visualize it), meaning that a triangle with two acute angles will only sometimes be an acute angle (when those two angles add up to an angle measure more than 90, meaning that the last angle will also be less than 90, making an acute triangle).

Hope this helps!

Help please and how to did it cuz I’m confused

Brrunno [24]

Answer:

-125

Step-by-step explanation:

Step 1: Find g(-1)

g(x) = -5x²

g(-1) = -5(-1)²

g(-1) = -5(1)

g(-1) = -5

Step 2: Find g(-5)

g(-5) = -5(-5)²

g(-5) = -5(25)

g(-5) = -125

Lacy work 15 hours last week she was paid $127.50 what is your hourly pay

kondor19780726 [428]

Given:

Lacy work 15 hours last week and she was paid $127.50.

To find:

The hourly pay of Lacy.

Solution:

We have,

15 hours pay = $127.50

To find the hourly pay of Lacy, we need to divide total pay by number of hours.

$\text{Hourly pay}=\dfrac{\text{Total pay}}{\text{Number of hours}}$

$\text{Hourly pay}=\dfrac{127.50}{15}$

$\text{Hourly pay}=8.5$

Therefore, the hourly pay of Lacy is $8.50.

Use 3.1 < sqrt 10 <3.2 to find the possible values of each expression. 2+sqrt 10

lilavasa [31]

The inequality which represents possible values of the expression 2+sqrt 10 by virtue of the given inequality; 3.1 < sqrt 10 < 3.2 as in the task content is; 5.1 < 2 + sqrt 10 < 5.2.

<h3>Which inequality correctly expresses the possible values of the expression; 2 + √10 as required in the task content?</h3>

It follows from the task content that the expression given is;

3.1 < sqrt 10 < 3.2

Since the given premises is an inequality, it follows that adding the same number to all parts of the inequality stills holds the inequality true.

Hence by adding 2 to all parts of the inequality, we have;

2 + 3.1 < 2 + sqrt 10 < 2 + 3.2

Therefore, we have;

5.1 < 2 + sqrt 10 < 5.2

Ultimately, 5.1 < 2 + sqrt 10 < 5.2 represent the possible values of the expression 2+sqrt 10 as given by the inequality 3.1 < sqrt 10 < 3.2.
