If LM = MK, LK =7x-10, KN = x+3, MN = 9x-11, and KJ =28, find LJ
marusya05 [52]

Answer:


Step-by-step explanation:

Suppose J, K, L, M, N are points on the same line.


MK = MN + (-KN) = MN - KN = 9x - 11 - x - 3 = 8x - 14


Since LK = MK and LK = 7x - 10, then


7x - 10 = 8x - 14


8x - 7x = -10 + 14


x = 4


LJ = MK + KJ


MK = LK = 7x - 10 = 7(4) - 10 = 28 - 10 = 18


LJ = 18 + 28 = 46

Find the missing side. Round to<br> the nearest tenth.<br> Х<br> 28°<br> 15<br> x = [?]
Effectus [21]

Given:

The right triangle with base 15 and hypotenuse x.

The measure of angle between base and hypotenuse is 28 degrees.

To find:

The value of x.

Solution:

In a right angle triangle,

\cos \theta=\dfrac{Base}{Hypotenuse}

In the given triangle,

\cos 28^\circ=\dfrac{15}{x}

x=\dfrac{15}{\cos 28^\circ}

x=\dfrac{15}{0.8829476}

x=16.98855

Round the value to the nearest tenth.

x\approx 17.0

Therefore, the value of x is 17.0 units.
