Are you asking what it was decreased by? Because if you are just do 325-128 and you get 197
The <em><u>correct answer</u></em> is:
16°.
Explanation:
The sum of the measures of the angles of a triangle is 180°. The two angles we have are 92° and 72°; together, these total to
92+72 = 164
This leaves us
180-164 = 16° for the remaining angle of the triangle.
X + 2 (2x + 20) = 85
x + 4x + 40 = 85
5x + 40 = 85
5x = 45
x = 9
12y + 6 + 32y = 2y - 6y - 30
44y + 6 = -4y -30
48y = -36
y = -36/48
y = -3/4
If solving for y:
→ 2x + y = 8
→ Take away 2x from both sides
→ y = 8 - 2x
If solving for x:
→ 2x + y = 8
→ Take away y from both sides
→ 2x = 8 - y
→ Divide both sides by 2
→ x =
