Answer : -5
Step by Step Explanation:
You first combine like terms which is -38 and 7, so subtract the 7 from the right and add it to -38.
That will give you 45. Then divide 9x and -45 by 9. That will give you -5
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
Amplitude is 4. Take the absolute value of value a
