PLS HELP ME!!!!!!!! 99 POINTS

Amiraneli [1.4K]

Answer:

$\angle LKN=\arctan1.8\sqrt{97}\approx 86.77^{\circ}$

Step-by-step explanation:

Draw the second altitude MB (see attached diagram).

Quadrilateral HLMB is a rectangle, then LM = HB = 3 units.

Trapezoid KLMN is isosceles trapezoid (because KL=MN), thus

$KH = BN = \dfrac{KN-HB}{2}=\dfrac{13-3}{2}=5\ units\\ \\HN=HB+BN=3+5=8\ units$

Triangle LHN is right triangle, then by Pythagorean theorem,

$LN^2=LH^2+HN^2\\ \\89^2=LH^2+8^2\\ \\LH^2=89^2-8^2\\ \\LH^2=(89-8)(89+8)\\ \\LH^2=81\cdot 97\\ \\LH=9\sqrt{97}\ units$

Consider right triangle KLH. In this triangle,

$\tan\angle LKH=\{\tan\angle LKH\}=\dfrac{\text{opposite leg}}{\text{adjacent leg}}=\dfrac{LH}{KH}=\dfrac{9\sqrt{97}}{5}=1.8\sqrt{97}\ units$

So,

$\angle LKN=\arctan1.8\sqrt{97}\approx 86.77^{\circ}$

Gabrielle's age is three times Mikhail's age. The sum of their ages is 56, what is their age?

My name is Ann [436]

G=3M

G+M=56

-------------------------------------------

3M+M=56

4M=56

M=56/4=14

---------------------------------------------

G+14=56

G=42

---------------------------------------------

So Gabriel is 42 and Mikhail is 14.

Are the two figures similar? If so, give the similarity ratio of the smaller figure to the larger figure.

TEA [102]

Answer: Yes they are similar and the ratio is 1 to 3

Step-by-step explanation:

They are similar because they are the same shape and the ratio is 3 because you can multiply each side by 3 to get the other figure's length.
