Question

Help pls !! this is my trig test btw ​

Answer 1

Required Answer:-

This is an right angle ∆ and the side lengths containing a right angle are 54 cm and 85 cm.

By Pythagoras theoram,

${a}^{2} + {b}^{2} = {c}^{2}$

where a is the perpendicular, b is the base and c is the hypotenuse.

Plugging the values,

${54}^{2} + {85}^{2} = {h}^{2}$

Then,

$h = \sqrt{ {54}^{2} + {85}^{2} }$

$h = 100.70 cm(approx.)$

Hence:-

The x of the right angled ∆ = 100.70 cm
