Respuesta :
The longest side is a 90° which is seven so the 30° is twice a small which is 3.5 in the 60° is 3.5 square root of three
The sides of the triangle 30-60-90 are 7/2 , 7/2*√3 and 7.
What is ?
The is a triangle, that has one of its interior angles equal to 90 degrees or any one angle is right angle.
Here, in the 30-60-90 ∆PQR
<R =30 , <P =60 and <Q =90
As we know, The length of the which is opposite to 90 is
Side PR = 7
As per the Theorem, the side opposite to the 30 angle is
Side PQ = 1/2* PR
Side PQ = 7/2
And, the side opposite to 60 angle is
Side QR = √3PQ
Side QR = 7/2*√3
Hence, The side’s of 30-60-90 are 7/2 , 7/2*√3 and 7 respectively.
