In triangle △JKL, ∠JKL is right angle, and KM is an altitude. JK=24 and JM=18, find JL.
PolarNik [594]

Answer:

JL ≈ 32  

Step-by-step explanation:

The triangle JKL  has a side of JK = 24 and we are asked to find side JL. The triangle JKL is a right angle triangle.

Let us find side the angle J first from the  triangle JKM. Angle JMN is 90°(angle on a straight line).

using the cosine ratio

cos J = adjacent/hypotenuse

cos J = 18/24

cos J = 0.75

J = cos⁻¹ 0.75

J = 41.4096221093

J ≈ 41.41°

Let us find the third angle L of the triangle JKL .Sum of angle in a triangle = 180°. Therefore,  180 - 41.41 - 90 = 48.59

Angle L = 48.59 °.

Using sine ratio

sin 48.59 ° = opposite/hypotenuse

sin 48.59 ° = 24/JL

cross multiply

JL sin 48.59 ° = 24

divide both sides by sin 48.59 °

JL = 24/sin 48.59 °

JL = 24/0.74999563751

JL = 32.0001861339

JL ≈ 32

In this polygon, which angle is an exterior angle?
Zigmanuir [339]

Answer:

The correct answer would be: D

Step-by-step explanation:

C is an interior angle, so it is out of question.

That leaves D, A, and B.

A and B are not correctly put in my opinion, because both angles are put in a circle probably suggesting it is equal to 360°, even though a whole trapeziods exterior angle alone is not supposed to equal to 360° because the entirety of it is supposed to be equivalent to that amount.

Leaving D, being the correct answer

I hope this helps

Some examples of additions with integers with 5 terms or more are:

  • 20 + 1 + 1 + 2 + 1= 25
  • 2 + 1 + 1 + 2 + 1= 7
  • 20 + 2 + 1 + 2 + 1= 26
  • 20 + 1 + 1 + 3 + 1= 26
  • 20 + 1 + 1 + 4 + 1= 27
  • 200 + 1 + 1 + 2 + 1= 205

<h3>What is an Integer?</h3>

In mathematics, an integer is a whole number that is used to represent a value and is not a fraction.

Furthermore, we can make the addition of integers as they would increment based on the number they are being incremented with and this has been shown above.
