Answer:
g=18.6
Step-by-step explanation:
-11-79+5g=3
-90+5g=3
5g=3+90
5g=93
g=93/5=18.6
g=18.6
Answer:24
Step-by-step explanation:Least common multiple (LCM) of 8 and 12 is 24.

and surely you know how much that is.
Since the exterior angle of a triangle is equal to the sum of the interior opposite angles, angle 5 = 90 + angle 1.
Given that angle 5 = 147, 147 = 90 + x.
x = 57 degrees.
So, angle 1 is 57 degrees.
