Given Information and To Find
It is given that in a right angled-triangle lmn,
∠m = 90°
∠l = x°
ln = 20 units
lm = 3b units
![secx = \frac{5}{3}](https://tex.z-dn.net/?f=secx%20%3D%20%5Cfrac%7B5%7D%7B3%7D)
We have to find the value of b.
What is a right-angled triangle?
A right triangle is a triangle in which one of the angles is at a right angle or two of the sides are perpendicular, or more formally, an orthogonal triangle, formerly known as a right-angled triangle. Trigonometry's fundamental concept is the relationship between a right triangle's sides and other angles.
Applying Trigonometry
We know that in a right angled-triangle,
![sec x=\frac{hypotenuse}{base}](https://tex.z-dn.net/?f=sec%20x%3D%5Cfrac%7Bhypotenuse%7D%7Bbase%7D)
In this case, we have (refer to the diagram),
![secx=\frac{ln}{lm}](https://tex.z-dn.net/?f=secx%3D%5Cfrac%7Bln%7D%7Blm%7D)
⇒ ![\frac{20}{3b} = \frac{5}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B20%7D%7B3b%7D%20%3D%20%5Cfrac%7B5%7D%7B3%7D)
⇒ ![20(3) = 3b(5)](https://tex.z-dn.net/?f=20%283%29%20%3D%203b%285%29)
⇒ ![15b = 60](https://tex.z-dn.net/?f=15b%20%3D%2060)
⇒ ![b=4](https://tex.z-dn.net/?f=b%3D4)

Answer:
7 to 8 hours
Step-by-step explanation:
1 * 4 = 4
5 / 6 * 4 = 20 / 6 = 3 2/6 or 3 1/3
4 + 3 1/3 = 7 1/3
