Answer: x = - 8

Step-by-step explanation:

\frac{x}{7+x} = 8

cross multiplying , we have

8 ( 7 + x) = x

Expanding the Left  Hand Side of the equation , we have :

56 + 8x = x collecting the like terms , we have

56 = x - 8x

56 = -7x

dividing through by - 7 we have :

- 8 = x  

Therefore :

x = -8

If the measure of angle 2 is 92 degrees and the measure of angle 4 is (one-half x) degrees, what is the value of x?
zavuch27 [327]

Answer: x = 184°

Step-by-step explanation: As we can see in the figure below, angles 2 and 4 are <u>Vertical</u> <u>Angles</u>, i.e., they are angles opposite each other when two lines cross. Vertical angles are always congruent.

Then,

m∠2 = m∠4

92=x.(\frac{1}{2})

92=\frac{x}{2}

Value of x is

x=92(2)

x = 184

The value of x is 184°.
