Answer:
x = 15, 72 degrees
Step-by-step explanation:
4x + 12 + 108 = 180
4x + 120 = 180
4x (+ 120 - 120) = 180 - 120
4x = 60
4x/4 = 60/4
x = 15
4x + 12
4(15) + 12
60 + 12
72 degrees
Answer:
see explanation
Step-by-step explanation:
A
given
= 
( cross- multiply )
5.7f = 34.2 ( divide both sides by 5.7 )
f = 6
-----------------------------------------------------
B
given
= 
( cross- multiply )
3.6g = 92.34 ( divide both sides by 3.6 )
g = 25.65
In mathematics, a plane is a flat, two-dimensional surface that extends infinitely far. A plane is the two-dimensional analogue of a point (zero dimensions), a line (one dimension) and three-dimensional space. which would be the same in geo.
