In the accompanying diagram of right triangle ABC, the hypotenuse if AB, AC = 3, BC = 4, and AB = 5. Sin B is equal to

Trava [24]

Answer: $sin(B)=\frac{3}{5}$

Step-by-step explanation:

We are given that a triangle ABC is a Right Angled Triangle. The side AB is hypotenuse, so the angle opposite to side AB which will be angle C is a Right Angle (measures 90 degrees)

We have the side length of all 3 sides. Based on this information, we can construct a triangle with given measures. The triangle is shown in the attached image.

We have to find the value of Sin(B). Sin of an angle is defined as:

$sin(\theta)=\frac{\text{Opposite Side}}{\text{Hypotenuse}}$

The side opposite to angle B is AC with a length of 3 and hypotenuse is side AB with length 5. So Sin of angle B would be:

$sin(B)=\frac{3}{5}$

Find value of x and y

marshall27 [118]

Answer:

x = 17 $\sqrt{3}$ , y = 34

Step-by-step explanation:

Since the triangle is right use trig ratios to find x and y

note exact values sin30° = $\frac{1}{2}$ , tan30° = $\frac{1}{\sqrt{3} }$

sin30° = $\frac{opposite}{hypotenuse}$ = $\frac{17}{y}$

multiply both sides by y

y sin30° = 17 ( divide both sides by sin30° )

y = $\frac{17}{\frac{1}{2} }$ = 34

tan30° = $\frac{opposite}{adjacent}$ = $\frac{17}{x}$

multiply both sides by x

x tan30° = 17 ( divide both sides by tan30° )

x = $\frac{17}{\frac{1}{\sqrt{3} } }$ = 17 $\sqrt{3}$
