Please help me with Geometry.

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

step-by-step explanation:

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
