Answer:
x=4
Step-by-step explanation:
3x-5 = 7

3x = 12
Divide each side by 3
3x/3 = 12/3
x = 4

2/3. 1/2 is equal to 3/6 and 3/6 + 1/6 is 4/6 and 4/6 simplified is 2/3.
67.38 degrees
To find this, follow the steps below:
cos (B) = 5/13
cos -1 (cos(B)) = cos-1 (5/13)
The cos-1 and cos cancel each other out.
B = cos-1 (5/13)
B = 67.38
