If the length of AB=12, what is the length of AP?
lara31 [8.8K]

Answer:

AP= 12

Step-by-step explanation:

Here is the complete question: If the length of AB=12, what is the length of AP? picture attached.

Given: AB= 12

          ∠APB= 60°

Remember; sum of all angle of triangle is equal to 180°.

We can look at picture, where two side of triangle is radius of circle.

∴ Angle of two side will also be same for the isosceles triangle.

Lets assume the unknow angle of the triangle be "x".

Now, x+x+60= 180

⇒ 2x+60= 180

subtracting both side by 60

⇒ 2x= 120

∴ x= 60

As now we have all the angle of triangle is 60° (equilateral triangle)

∴ All the side will be same, which is 12

Hence, AP= 12.

To prove that ΔAED ˜ ΔACB by SAS, Jose shows that StartFraction A E Over A C EndFraction = StartFraction A D Over A B EndFractio
stich3 [128]

The other equality which must be stated by Jose is that angles BAC and BAE are congruent and their measures are equal.

<h3>What other congruence statements must Jose state?</h3>

It follows from the task content that Jose is trying to prove the congruence of both triangles by means of the Side-Angle-Side congruence theorem.

It therefore follows that since, Jose has identified that the ratio of corresponding sides are equal as indicated in the task content, the equality which Jose has to state is the angle congruence equality.

A plane is descending onto the runway with an angle of depression of 55°. If it has 2.8 miles to go before landing (hypotenuse),
nalin [4]

Answer:

Option C is correct

Step-by-step explanation:

Given: A plane is descending onto the runway with an angle of depression of 55°. Also, it has 2.8 miles to go before landing.

To find: current altitude of the plane

Solution:

Consider the attached image.

In ΔABC,

\angle ACB=55^{\circ} (Alternate interior angles)

For any angle \theta,

tan \theta = side opposite to angle/side adjacent to angle

\tan C=\frac{AB}{BC}

Put \angle C=55^{\circ}\,,\,BC=2.8\,\,miles

AB=2.8\,\tan 55^{\circ}=3.999\approx 4\,\,miles

So, the current altitude of the plane is 4 miles.
