Answer:
x + 27 = - 12
x = - 39
Step-by-step explanation:
The perimeter of the triangle, rounded to the nearest tenth, is 8.5 units.
It is four. So two and two you add them together to be four. Good job. Your learning :)
M<GJI=(x+60)°=?
We need to find x. The angle GJI and FJH are opposite by the the vertex, then they must be congruents:
(x+60)°=(5x)°
x+60=5x
Solving for x
x+60-x=5x-x
60=4x
60/4=4x/4
15=x
x=15
Replacing x by 15 in m<GJI:
m<GJI=(x+60)°=(15+60)°→m<GJI=75°
Answer: Option b. 75
