Find the area of △LKJ.
nirvana33 [79]

Answer:

A=600\: u^{2}

<u>The correct answer is letter c.</u>

Step-by-step explanation:

The area equation of a triangle is given by:

A=\frac{bh}{2}  (1)

Where:

b is the base

h is the height

Let's find first the angle MJK (α), using the tangent definition.

tan(\alpha)=\frac{24}{32}

\alpha=tan^{-1}(\frac{24}{32})

\alpha=36.9^{\circ}

Now, if α = 37° then β (angle JLK) must be:

37^{\circ} + \beta + 90^{\circ}=180^{\circ}

\beta=53^{\circ}

Now, we can find the distance ML using again the tangent definition:

tan(\beta)=\frac{24}{ML}

ML=\frac{24}{tan(53)}

ML=18

The base of the triangle LKJ will be:

b=32+ML=32+18=50

Therefore, using equation (1) the area of △LKJ will be:

A=\frac{50*24}{2}

A=600\: u^{2}

The correct answer is c.

I hope it helps you!

Name two similar triangles shown in the figure. explain why the triangles are similar
DochEvi [55]
The two similar triangles are triangle BXY and triangle BAC. Since line XY is parallel to segment AC, angle BXY is congruent to angle A, and angle BYX is congruent to angle C. Since two corresponding angles are congruent, we use one of our similarity conjectures, Angle-Angle, to show these triangles are congruent.

Noah built a fenced dog run that is 8 yards long and 6 yards wide. He placed posts at every corner and every yard along the leng
bagirrra123 [75]
To solve this problem first find the perimeter of the rectangle by using the formula P= 2(L+W).
Plug in your number and you get the number 28.
Now, because Noah is putting in a post at every yard and our answer is already in yards we are done.

Noah will need 28 post to build the dog run.

P=2(8+6)
P=2(14)
P=28

Hope this helps :-)
