X + 12 = 30
Reorder the terms:
12 + X = 30
Solving
12 + X = 30
Solving for variable 'X'.
Move all terms containing X to the left, all other terms to the right.
Add '-12' to each side of the equation.
12 + -12 + X = 30 + -12
Combine like terms: 12 + -12 = 0
0 + X = 30 + -12
X = 30 + -12
Combine like terms: 30 + -12 = 18
X = 18
Simplifying
X = 18</span>

C
Step-by-step explanation:
<u>Answer:</u>
143°
option c is correct!
<u>Explanation:</u>
Given:
Two angles are supplementary:
One angle = 37°
We know if two angles are supplementary their sum is equal to 180°.
Let another angle be x°
= > 37° + x° = 180
= > x° = 143°
Therefore another angle is 143°.
Answer:
$72,100
Step-by-step explanation:
To calculate the total principal+interest payment, you can use the formula to find the future value:
FV=PV(1+i)^n
FV= Future value
PV= Present value= $58,200
i= Interest rate= 7.40%
n= Number of periods of time= 3 years
Now, you can replace the values on the formula:
FV=58,200*(1+0.0740)^3
FV=58,200*(1.0740)^3
FV=72,100
According to this, the answer is that the total principal + interest payment will be $72,100.
Answer:
Step-by-step explanation:
tan47=x/18
x=18tan47
cosCDB=7/x
cosCDB=7/(18tan47)
CDB=arccos(7/(18tan47))
CDB=68.74
