.. x = 2.75 +78/8 = 12.50
Answer:
Length of side QR is 16 units.
Step-by-step explanation:
Given that dimensions of are as follows:
Side QP
Side PR = 8 units
To find, side QR = ? units
Please refer to the attached figure for the representation of the given dimensions.
Base is side QP,
Perpendicular is side PR and
Hypotenuse is side QR.
In a right angled triangle, Pythagorean theorem holds true i.e.
Accoring to pythagoras theorem:
Putting the values of QP and PR:
So, the value of length of side <em>QR is 16 units</em>.
