Answer: Choice A) Obtuse

The angle 126 degrees is larger than 90 degrees. Any time you have a triangle with one angle larger than 90 degrees, you'll always have an obtuse triangle. This is by definition of what "obtuse triangle" means.

Answer:

Obtuse triangle

Step-by-step explanation:

Obtuse angle:When the angle is greater than 90 degrees and less than 180 degrees then, the angle is called  obtuse angle.

Acute angle: When the angle is less than 90 degrees then the angle is called acute angle.

Right angle: When the angle is equal to 90 degrees then, the angle is called right angle

Obtuse triangle: When one angle of triangle is obtuse then, the triangle is called obtuse triangle.

Acute triangle: When all angles of triangle are acute then, the triangle is called acute triangle.

Right triangle: When one angle of triangle is right angle then, the angle is called right triangle.

We are given measurements of angles of a triangle are

30^{\circ},24^{\circ},126^{\circ}

126 degrees is greater than 90 and less than 180 degrees , therefore it is an obtuse angle.

Therefore, given triangle is an obtuse triangle because one angle of given triangle is obtuse .

Hence, given triangle is an obtuse triangle.

6. what is the parimeter of triangle ABC<br>8. What is the value of x​
nalin [4]

<u>Answer:</u>

Perimeter = 20 units

x = 120°

<u>Step-by-step explanation:</u>

We are given a triangle ABC with known side lengths for all three sides and an inscribed circle.

We are to find the perimeter of triangle ABC and the value of x.

Perimeter of triangle ABC = 2 + 2 + 5 + 5 + 3 + 3 = 20 units

The kite shape at the end is a quadrilateral which has a sum of angles of 360 degrees.

Two out of four angles are right angles and one is 60 so we can find the value of x.

x = 360 - (90 + 90 + 60) = 120°

Which function has a vertex at the origin?
dlinn [17]

Answer:

  (d)  f(x) = -x²

Step-by-step explanation:

For the vertex of the quadratic function to be at the origin, both the x-term and the constant must be zero. That is, the function must be of the form ...

  f(x) = a(x -h)² +k . . . . . . . . . . vertex form; vertex at (h, k)

  f(x) = a(x -0)² +0 = ax² . . . . . vertex at the origin, (h, k) = (0, 0)

Of the offered answer choices, the only one with a vertex at the origin is ...

  f(x) = -x² . . . . . a=-1

The function below shows the number of car owners f(t), in thousands, in a city in different years t: f(t) = 0.25t2 − 0.5t + 3.5
N76 [4]
We solve this by the definition of slope in analytical geometry. The definition of slope is the rise over run. In equation, that would be

m = Δy/Δx = (y₂-y₁)/(x₂-x₁)

The x-coordinates here are the t values, while the y-coordinates are the f(t) values. So, let's find the y values of the boundaries.

At t=2: f(t)= 0.25(2)²<span> − 0.5(2) + 3.5 = 3.5
Point 1 is (2, 3.5)
At t=6: </span>f(t)= 0.25(6)² − 0.5(6) + 3.5 = 9.5
Point 2 is (6, 9.5)

The slope would then be

m = (9.5-3.5)/(6-2)
m = 1.5

Hence, the slope is 1.5. Interpreting the data, the rate of change between t=2 and t=6 is 1.5 thousands per year.
