const2013 [10]3 years ago
5 0

Answer:

m∠DFC=80°

Option 2 is correct

Step-by-step explanation:

In the given figure, BE and AD are straight line.

If two lines intersect then makes vertically opposite angles.

Therefore,

\angle AFE=\angle BFD

But ∠AFE=125°

We can split ∠BFD into two adjacent angle.

\angle DFC+\angle BFC=\angle BFD

but ∠BFC=45°

Therefore,

\angle DFC+45^\circ=125^\circ

\angle DFC=125^\circ-45^\circ

\angle DFC=80^\circ

Hence, The angle DFC is 80°

What is the sum of the lengths, in centimeters, of the two legs of a 30-60-90 right triangle, if the length of the hypotenuse is
Nesterboy [21]

The sum of the lengths of two legs of the 30°-60°-90° right triangle is 6.69 centimeters. Using the ratio of sides for the 30°-60°-90° triangle, the sum is calculated.

<h3>What is the ratio of sides for the 30°-60°-90° triangle?</h3>

The ratio for the 30°-60°-90° triangle is 1:√3:2 or x:x√3:2x

where x corresponds to the length opposite the 30° angle and x√3 is opposite of the 60° angle and 2x is opposite to the 90° angle.

<h3 /><h3>Calculation:</h3>

It is given that the triangle is a right triangle with angles 30°-60°-90°

For such a triangle, the ratio of side lengths is x: x\sqrt{3}:2x

we have the length of the hypotenuse is 2\sqrt{6}

So, 2x = 2\sqrt{6}

⇒ x = \sqrt{6}

So,

the other length of the other leg is x√3 = √6 × √3 = 3 √2

Then, the sum of these two legs = √6 + 3√2 = 6.69 centimeters.
