How do you classify a triangle

Mathematics
1 answer:
Tems11 [23]3 years ago
5 0
It is based off of the angles of the triangle and the sides.
A triangle with a right angle (90°) is a right triangle.
A triangle with an angle larger than 90° is an obtuse triangle.
A triangle with angles that are smaller than 90° is an acute triangle. ALL ANGLES MUST BE SMALLER THAN 90°...

With sides, if a triangle has two angles that equal the same length, it is an isosceles triangle.
If NO sides are of equal length, it is a scalene triangle.
And if ALL sides are equal, then it is a equilateral triangle.

Evaluate (3.5×10^13)-(1.4×10^12)/3×10^9
maw [93]

Answer:

11,200

Step-by-step explanation:

At first we use "BODMAS" rule.

Given,

(3.5×10^13)-(1.4×10^12)/3×10^9

So, we will break the brackets at first. With the help of excel, we can get the desired result. The following images will show you the step-by-step result.

Use "Number" instead of "general" in the excel sheet. You can use calculator too.

Find the length of an arc made by a 180-degree central angle in a circle with a 10ft radius
mixas84 [53]

Answer:

the length of an arc = 10π ft.

Step-by-step explanation:

The length of an arc with angle Θ and radius r will be equal r * Θ

note the angle must be in radian

Given: Θ = 180° = π  and radius = r = 10 ft.

<u>So, the length of the arc = π * 10 = 10π ft.</u>

A laptop has a listed price of $703.98 before tax. If the sales tax rate is 9.25% , find the total cost of the laptop with sales
Jlenok [28]

Answer:

<h2>The cost of the laptop is $769.10</h2>

Step-by-step explanation:

In this problem we are required to find the cost of the laptop when 9.25% of the cost is added as tax

we are given that the tax rate is 9.25% of the initial cost

and the initial cost is $703.98

 let us calculate 9.25% of  $703.98

(9.25/100)* 703.98= 0.0925*703.98= $65.12

Hence the charges for tax is $65.12

The total cost of the laptop when tax is included is

the initial cost Plus the tax charges= $703.98+$65.12= $769.098

$769.10

A triangle has side lengths of ( 4h + 2k) centimeters, (9h + 4m) centimeters, and (2m - k) centimeters. Which expression represe
enot [183]

Answer:

P = (13h+k+6m) cm

Step-by-step explanation:

Given that,

The side lengths of a triangle are :

(4h + 2k) cm, (9h + 4m) cm, and (2m - k) cm

We need to find the perimeter of the triangle.

We know that,

Perimeter = sum of all sides

So,

P = (4h + 2k)+(9h + 4m)+(2m - k)

= (4h+9h)+(2k-k)+(4m+2m)

= 13h+k+6m

Hence, the perimeter of the triangle is (13h+k+6m) cm.
