Does 21.6,28.8,36 equal a right triangle

1 answer:

3 0

21.6 < 28.8 < 36

<span>if they are the lengths of the sides of a right triangle then:

$21.6^2+28.8^2=36^2\\\\L_s=466.56+829.44=1296\\\\R_s=1296\\\\L_s=R_s$

therefore it's the right triangle.</span>

In ΔDEF, \overline{DF} DF is extended through point F to point G, \text{m}\angle FDE = (2x+4)^{\circ}m∠FDE=(2x+4) ∘ , \text{m}\a

Sedaia [141]

Answer:

Step-by-step explanation:

See the diagram attached:

In a triangle, the sum of interior angles is equal to the exterior angle.

According the diagram, the sum of interior angles is given as:

Sum of interior = <FDE+<DEF

Given

<FDE = 2x+4

<DEF = 3x+5

Sum of interior = 2x+4+3x+5

Sum of interior = 5x+9

Exterior angle = <EFG = 7x-5

Equate the interior to the exterior and calculate the value of x:

5x+9 = 7x-5

Collect like terms

5x-7x = -5-9

-2x = -14

x = -14/-2

x = 7

Next is to get <FDE:

<FDE = 2x+4

<FDE = 2(7)+4

<FDE = 14+4

<FDE = 18°

Hence the measure of <FDE is 18°

All triangles add up to 180 degrees so I don’t get the just of the question but there you go.

X + 11 < 6 <br> Solve and graph on a number line

Drupady [299]

Answer & Step-by-step explanation:

So I can't exactly graph exactly, but I'll try...

To solve:

x+11<6 Subtract 11 on both sides.

x<-5

To graph:

<-------|---------o---------|-------->

-6 -5 -4

(The bolded part of the line is the side you shade the graph on. In case you can't see it, you have to shade the left side of the open circle.)

Hope this helps! Have an awesome day ( • ω • )^
