Answer:
option 2
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
7*x-4-(21)=0
Solve : 7x-25 = 0
Add 25 to both sides of the equation :
7x = 25
Divide both sides of the equation by 7:
x = 25/7 = 3.571
Answer:
42.3
Step-by-step explanation:
- Substitute in values

That is a 30 60 90 triangle
The "short" side (DE) equals the middle side (FE) times (1 / sq rt(3))
short side = 8 * sqrt(3) * (1 / sq rt(3) = 8
Hypotenuse (DF) is 2 times the short side which equals 16.

Answer: x = 148 degrees
Step-by-step explanation:
This problem makes use of Supplementary Angles. Supplementary Angles states that two angles that make up a line add to 180. Thus, simply use the equation 32 + x = 180
x = 148
