No because 5^2 +10^2 is not equavalent to 13^2
by using the pythagoras' theorem
If it’s X-27=62, you have to isolate X. So you would put your -27 on the other side but in doing that you have to change your negative 27 to a positive as it is switching sides. So it would now be, X=62+27, which is 89. Final answer, X=89
D= 3 2/5=3.4m
T= 7/8 = 0.875h
Use v = d / t. V= 3.4/0.875
V=3.866 mph
The angle of rotation for a regular polygon is 360/number of sides.Here, it is 360/20=18 degrees.
From the diagram, ΔRST, ΔRUS and ΔSUT are right triangles. This means that the corresponding legs of the three triangles are proportional, then we can say that the triangles are similar by side-angle-side similarity.
RS/RU=RU/SU
In the figure we can also notice that the acute angles of the corresponding angles are similar, then by angle-angle similarity the triangles are similar.
∠TRS~∠URS~TSU
This implies that: ΔSUT~ΔSRU~ΔRTS
