Question

Please help, would be greatful :)

Answer 1

h is approximately equal to 13.4

Explanation:

We can use the sine rule to solve this. We're told that the hypotenuse is 18 cm and we know that it's opposite a corner of 90 degrees. We also know that the corner opposite the side of length h has an angle of 48 degrees.

With that we can use the sine rule to solve for h:

`(h)/(sin(48)) = (18)/(sin(90))\\(h)/(sin(48)) = (18)/(1)\\h = 18 sin(48)\\h \approx 13.4`
