Answer:
52
Step-by-step explanation:
140 - 13 = 127
127 - 75 = 52
Check your work:
75 + 13 + 52
= 140
Answer:
If the sinø=7/12, cosø is 
Step-by-step explanation:
We are given sinФ = 7/12
We need to find cosФ
The basic trigonometric functions of right triangle are:


We need values of adjacent and hypotenuse to find cosФ
Using Pythagoras theorem we can find the value of adjacent

We have Hypotenuse= 12 and Opposite = 7 (because
and we are given 
Inserting values and finding adjacent:

So, value of Adjacent is 
Now finding cosФ

Adjacent =
, hypotenuse = 12

So, If the sinø=7/12, cosø is 
Answer is 20 by plugging the 4 in the equation it equals 20
Answer:
x = 3
Step-by-step explanation:
5x + 3 = 3x + 9
subtract 3 on both sides (cancels out 3) (inverse operation)
5x = 3x + 6
subtract 3x on both sides (cancels out 3x) (inverse operation)
2x = 6
divide both sides by 2 (isolates x) (simplifies)
x = 3
