There exists the same question with an attachment where angle 8 and 7 are supplementary and angle 7 and 5 are vertical angles. From this, the equation that we may derive from the given is,
(2x + 15) + (3x) = 180
The value of x is 33. Substitute this value to x of angle 7, 2(33) + 15 = 81. Thus, the measure of angle 5 is also 81 degrees.

The answer is:
Justin weighs 165 pounds.
Greg weighs 180 pounds.
If:
j - Justin's weight
g - Greg's weight
Then the system of equations is:
j + 15 = g ⇒ g = j + 15
1/2g = j - 75 ⇒ j = 1/2g + 75
We can replace j in the first equation:
g = <span>1/2g + 75 + 15
g - 1/2g = 90
1/2g = 90
</span>⇒ g = 90 ÷ 1/2 = 180
<span>
Thus, Greg weighs 180 pounds.
Now, using the first equation, we will calculate Justin's weight:
</span>j + 15 = g ⇒ j = g - 15
g = 180
Thus
<span>j = g - 15 = 180 - 15 = 165
</span>
Therefore, <span>Justin weighs 165 pounds.</span>
