Ответ:
The value is 62 degrees to the nearest degree
Step-by-step explanation:
In this question, we are asked to calculate the magnitude of the angle B.
From the diagram, we can see that we have a right-angled triangle. What this means is that the ratio of the sides can be used to get the other two angles in the triangle.
we have the opposite(side facing the angle) and the hypotenuse (longest side) in the triangle. Thus, the trigonometric identity to use is the sine
Mathematically;
The sine of an angle = length of the opposite/length of the hypotenuse
Where we have length of the opposite here as 15cm and the length of the hypotenuse here as 17cm
Sine B = 15cm/17cm
Sine B = 0.8824
B = arcsin (0.8824)
B = 61.92 degrees = 62 degrees to the nearest degree
Ответ:
