Answer:
50.528º
Step-by-step explanation:
tanA = BC/BA
tanA = 17/14
A = 50.528º
2x^2-2x
Step by Step Explanation:
The 2 x^2 come together to form 2x^2 and since there is no other number that has x but no ^2 -2x stays the same.
(3x + 1/2 ) + ( 7x - 4 1/2 )
3x+7x + 1/2 - 4 1/2
10x -4
. Solving it we find that x=63. And it is the final answer for this problem.
