If AB = 13, BC = 9, and CA = 17, list the angles in order from smallest to largest.

On the packaging for a triangular sail, the edge measurements for the sail are listed as 7 ft × 15 ft × 17 ft. Without unfurling

Answer:

Shape of Triangular sail is Obtuse Angled Triangle.

Step-by-step explanation:

The triangle is obtuse since the sum of the squares of 2 sides are greater than the square of the third side. (Converse Pythagorean theorem) Hope this helps!

Given: Length of sides of triangular sail = 7 ft , 15 ft , 7 ft

To find: Shape of Sail .i.e., shape of triangle

We use a result which states that

if a , b , c are sides of triangle where c is greater then a & b.

now, if c² < a² + b² then triangle is Acute angled

if c² = a² + b² then triangle is Right angled

if c² > a² + b² then triangle is Obtuse angled

here a = 7 , b = 7 & c = 15

c² = 15² = 225

a² + b² = 7² + 7² = 49 + 49 = 98

since, c² > a² + b²

⇒ Triangle must be Obtuse Angled.

Therefore, Shape of Triangular sail is Obtuse Angled Triangle.

Maria, Carolina and Pedro receives $1600 from their grandfather in ratio 7:5:4. calculate share of each.

Nimfa-mama [501]

Step-by-step explanation:

here's your solution

=> total money received by them = $1600

=> the given ratio are 7:5:4

=> let the ratio be X ,now

=> Maria = 7X

=> Carolina = 5X

=> Pedro = 4X

=> we know whole money = $1600

=> so, adding all

=>. 7x + 5x + 4x = $1600

=> 16x = $1600

=> x= $1600/16

=>. x = $100

now Maria = 7*100 = $700

Carolina = 5*100 = $500

Pedro = 4*100 = $400

hope it helps

Will someone please help me with this because I don't understand and I don't want to fail my class.

Answer:

4y + 1 = 4 - 5y

First option

Step-by-step explanation:

x - 4y - 1 =0; add both sides by + 4y + 1

x - 4y - 1 + 4y + 1 = 0 + 4y + 1

Simplifying

x = 4y + 1

x + 5y - 4 = 0; Add (-5y + 4) to both sides

x + 5y - 4 -5y + 4 = 0 -5y + 4

Simplying

x = -5y +4

x = 4 - 5y

Now you have both equations

x = 4y + 1

x= 4 - 5y

Now you can use the comparison method

4y + 1 = 4 - 5y
