The new equation is 
Explanation:
The equation is 
We need to determine the new equation by adding 16 to both sides of the equation.
Hence, we shall increase both sides of the equation
by 16, we get,

Adding, we get,

Hence, the new equation is 
Answer:
22 degrees to the nearest degree.
Step-by-step explanation:
Use the Cosine Rule
3^2 = 5^2 + 7^2 - 2*5*7*cos T
9 = 74 - 70 cos T
cos T = (74-9)/ 70
cos T = 65/70
m < T = 21.8 degrees.
Answer:
simplifying
