Answer 1

In the triangle with legs 7 and 9 cm, you can find the length of the hypotenuse by using the Pythagorean theorem. If the hypotenuse is
`x`, then

`7^2+9^2=x^2\implies x=√(130)`

The other right triangle with leg 6 cm and containing the angle
`\theta` satisfies

`\sin\theta=(6\,\rm cm)/(√(130)\,\rm cm)\implies\theta=\sin^(-1)\frac6{√(130)}\approx31.75^\circ`
