Question

Please help, would be greatful :)

Answer 1

Answer:

h is approximately equal to 13.4

Step-by-step 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:

$\frac{h}{sin(48)} = \frac{18}{sin(90)}\\\frac{h}{sin(48)} = \frac{18}{1}\\h = 18 sin(48)\\h \approx 13.4$
