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}

Kamila [148]
Answer:

s= 10 + 2.50w

explanation:

the amount of money in your savings is equal to the initial $10 you had before you started saving 2.50 per week. weak week $2.50 is added to the savings. 2.50w can be seen as 2.50 times the amount of weeks. say you were 3 weeks into saving, you would do 10 + 2.50(3) to find the amount of money you have.

Find the correct prime factorization of 28/98, and then reduce the fraction to lowest terms. ...?
ycow [4]
In math, prime factorization is defined as the <span>finding of the </span>prime<span> numbers that multiply together to make a particular number. A prime number is a number that is only divisible by itself and one. In this case, the correct prime factorization of 28/98 is </span><span>(2x2x7)/(2x7x7), and when you reduce the fraction to its lowest term, you will get 2/7. Hope this answer helps.</span>
