Youn could test all of the options by putting 8 and 3 in for a and b.

A. a - b = 5
8 - 3 = 5
5 = 5

B. a + b = 5
8 + 3 = 5
11 ≠ 5

C. a - b = 8
8 - 3 = 8
5 ≠ 8

D. a + b = 8
8 + 3 = 8
11 ≠ 8

As you can see, the only one that works is A. a - b = 5.

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

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:

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