# Right angled triangle with bottom side of the triangle is 40cm and the there are 2 angles attached to it, 40degrees and 90degrees, what is the length of the other 2 sides?

Given that a right angled triangle with bottom side of the triangle is 40cm and the there are 2 angles attached to it, 40degrees and 90degrees.

So adjacent w r to angle ${40}^{\circ}$ is $40$ cm.

So $\text{opposite"/"adjacent} = \tan {40}^{\circ}$

Hence $\text{opposite} = 40 \cdot \tan {40}^{\circ} = 33.56$ cm.

Again

$\text{hypotenuse"/"adjacent} = \sec {40}^{\circ}$

So $\text{hypotenuse} = 40 \cdot \sec {40}^{\circ} = 52.21$cm
