2x4 is the answer to 4x-2=38
It does not look like Suro even made an error. She took the square root of both sides to get x = 7, I don't see any problem here.
Answer: x=6
Step-by-step explanation:
3(x-2)=12
3x-6=12
3x=18
x=6
Answer: The tangent of the larger acute angle is 4/3 or 1⅓
Step-by-step explanation: if the sides of the right angled triangle are given as 3, 4 and 5 respectively, then the hypotenuse is 5 and the longer of the other two sides is 4. The angle facing the side measuring 4 is your reference angle, and that is the larger of the other two acute angles (see attachment)
Tan X = opposite/hypotenuse
Tan X = 4/3
Tan X = 1⅓
