Answer:
(4+1) x (12 x 7)
420
The only way to get this answer is to use trial and error
(f0g) = -2(x+7)+8
(f0g) = -2x-14+8
(f0g) = -2x-6
(f0g)(2) = -2(2)-6 = -4-6 = -10
(f0g)(2) = -10
hope this helps!
This question is too short not specific but if this is what u mean then it is 17.50
Answer:
The unknown angle = 126°
Step-by-step explanation:
From angles in a triangle.
The total sum of angles in a triangle = 180°
Let the unknown angle be x
27 + 27 + x = 180
X = 180-27-27
X= 180-54
X = 126°
