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.

Help please I’m confused

kipiarov [429]

Answer:

h = 5.4

Step-by-step explanation:

Basically these are 2 similar triangles. That means:

Corresponding sides are proportional.

We can set up a ratio of each triangle separately and equate, cross multiply and solve for "h".

h corresponds to 2.4

2.9 corresponds to 1.3

Setting up the ratio and solving for h:

$\frac{h}{2.4}=\frac{2.9}{1.3}\\1.3h=2.4*2.9\\1.3h=6.96\\h=\frac{6.96}{1.3}\\h=5.35$

Rounded to 1 decimal place,

h = 5.4

True or false: Every kite is a rhombus, but not every rhombus is a kite.

horsena [70]

This is false. Kites can be shaped in many different ways so not all kites are rhombuses. Also, even the kites that look like rhombuses may not be rhombuses. Most kites have 2 pairs of sides with the same length. But, in order to be a rhombus all the sides have to be the same length but not all sides are the same length on a typical kite.

Table:

Fynjy0 [20]

Answer:

2) Yes, each x-coordinate is only used once.

3) {1,2,3,4}

4) {25,45,60,70}

5) (3,60)

6) No because (4,7) and (4,25) share the same x-coordinate.

Step-by-step explanation:

A relation is a function if there is no more than one y-value assigned to an x.

Any x used can only be used once in an order pair.

You that here.

(1,25)

(2,45)

(3,60)

(4,70)

So basically because all of the x-coordinates are different, this is a function.

The domain is the x-coordinate of each pair (the first of each pair):

{1,2,3,4}.

The range is the y-coordinate of each pair (the second number of each pair):

{25,45,60,70}.

One ordered pair that I see in the table is (3,60). There are 3 others you can choose and I named them above.

{(4,10),(3,15),(1,5),(2,25),(4,25)} is not a function because there are more than one pairs with the same x-coordinate,4.

Find two number nearest to 8888888 which are exactly divisible by 2915

Marysya12 [62]

Step-by-step explanation:

Given problem is to find nearest number,

= 8888888/2915

quotient = 3049

remainder= 1053

Now, 2915-1053 = 1862

8888888+1862 = 8890750

8888888-1053 = 8887835

Two numbers nearest to 8888888 which are exactly divisible by 2915 is 8887835 and 8890750
