#

if the angles are in the ratio 2:3:5 you can call them 2x, 3x, 5x

analog plinth
#

Yeah

#

Do you make them equal to 180

#

Then solve for x

#

@formal magnet I think I got the first one

formal magnet
#

yes

#

nice

analog plinth
#

How do I get the second one tho?

formal magnet
#

you have that the shortest side is opposite the smallest angle

#

so you can use sin(angle) = opp/hyp

analog plinth
#

So would you have to use I)

#

To give you the opposite

formal magnet
#

use that they're in 2:3:5 ye

#

use the value calculated

analog plinth
#

I got 18:27:45

formal magnet
#

do those sum to 180?

analog plinth
#

The all add up to 90

formal magnet
#

they should add up to 180

analog plinth
#

Oh 180

formal magnet
#

mhm

analog plinth
#

They add up to 180

#

I solved for x then substituted

formal magnet
#

ik i can tell

analog plinth
#

So what do I do after that?

formal magnet
#

it just says show that there is a right angle

analog plinth
#

I see

#

But don’t right angle have to form 90 degrees

formal magnet
#

a right angle is 90 degrees

#

the angles in the triangle add up to 180

#

right-angled doesn't mean it adds up to 90, it means one of its 3 angles is 90

analog plinth
#

True

#

So what do I do after that
