Answer:
38 degrees
Step-by-step explanation:
By the Law of Cosines,
5² = 3² + 7² - 2(3)(7) cos A
5² - 3² - 7² = -2(3)(7) cos A
-33 = -42 cos A
cos A = 33/42
A = arccos(33/42), which is about 38 degrees.
It is unlikely is the expected answer. (<em>c</em><em>o</em><em>r</em><em>r</em><em>e</em><em>c</em><em>t</em><em> </em><em>o</em><em>n</em><em>e</em><em>)</em>
Hope this helps.
If you Multiply the equation you will get 9x+11
Add 21 to both sides, then that means you get
K>22
there is no need to change the signs, as you are not multiplying by a negative or anything
