Answer:
1) <em><u>26.</u></em><em><u>1</u></em><em><u>% increase</u></em>
2) <em><u>20% decrease</u></em>
Work:
1)
-subtract the larger # from the smaller # to figure out what the change was.
-divide 2.3 by the orriginal ammount (8.8) to find your answer as a decimal
-take 0.261 and multiply it by 100 to have your answer as a percent
-if the original number increased than it is percent increase and if the original number decreased than it is percent decrease

Answer: 48 degrees

See the attached image for a visual of the problem and answer.
Based on the diagram, we have angle AHB = 132 degrees (given) equal in measure to angle XHY since these two angles are vertical angles.
Angles HYC and HXC are right angles due to the nature of AX and BY being altitudes. Recall that altitudes are segments that go from one vertex to the opposite side and they are perpendicular to the opposite side.
Focus on quadrilateral HXCY. So far, we know that...
Angle XHY = 132 degrees
Angle HYC = 90 degrees
Angle HXC = 90 degrees
The angle we want to find is angle ACB, which is the same as angle YCX. This angle is the missing angle of the quadrilateral HXCY.
For any quadrilateral, the four angles must add to 360 degrees.
(angle XHY) + (angle HYC) + (angle HXC) + (angle YCX) = 360
(132) + (90) + (90) + (angle YCX) = 360
312 + (angle YCX) = 360
312 + (angle YCX) - 312 = 360 - 312
angle YCX = 48 degrees
Since angle ACB is the same as angle YCX, we can say
angle ACB = angle YCX = 48 degrees
So in summary,
angle ACB = 48 degrees
