Answer:
x = 180 - [(180 - 3x) + (180 - 2x)]
Step-by-step explanation:
Start off by finding the angles of the triangle
Angle F = 180 - 3x
The angle across from I (which I will call I) = 180 - 2x
Angle G = 180 - (F + I)
Now that we know what G is, we know what x is because the Alternate Exterior Angles Theorem states that if a pair of parallel lines are cut by a transversal, then the alternate exterior angles are congruent. So pretty much X = G
Therefore x = 180 - (F + I) or otherwise said as:
x = 180 - [(180 - 3x) + (180 - 2x)]
I hope this is helpful :)
Answer:
I'm guessing A
sorry if I'm wrong

Answer:
None of the above.
Step-by-step explanation:
A. (7 * 4) + (0.5 * 7) = 31.5.
B. (7 + 4) * (0.5 + 4) = 49.5
C. (7 x 4) + (0.5 x 4) = 30.
D. (7 x 4) x (0.5 x 4) = 56.
All of these do not answer 7.5, so your answer is none of the above.
hope this helps.
