Answer:
63
Step-by-step explanation:
Answer:
60
Step-by-step explanation:
Cot is the same as 1/tan so:
By rearranging the equation, we get:
By taking the inverse tan, we get:
If you are solving for X then we have to do a few process
What you would want most is to remove the parentheses, so to do that i would use distributive property
3*2x is 6x and 3*3 is 9 so our new equation will look like
6x+9=15 if you don't understand please tell me
now we must bring the 9 over
If you bring the 9 over than it would become negative
6x=15-9
so 6x=6
and now you can solve the answer is x=1
Answer:
x = 8.45
Step-by-step explanation:
5.4 + 0.2x = 7.09
Subtract 5.4 from both sides to leave 0.2x alone
0.2x = 1.69
Divide by 0.2 on both sides to isolate x
x = 1.69/0.2
x = 8.45
