Answer:
All sides are the same length (congruent) and all interior angles are the same size (congruent). To find the measure of the angles, we know that the sum of all the angles is 1260 degrees (from above)... And there are nine angles... So, the measure of the angle of a regular nonagon is 140 degrees.
Step-by-step explanation:
Although there is no picture, I will assume this is a triangle we are talking about since the terms base and height are being used. If that is the case, the height is roughly 38.72in.
To find this, we will use the area of a triangle formula.
1/2bh = a ---> plug in known values.
1/2(12.6)(h) = 244 ---> multiply to simplify
6.3(h) = 244 ----> divide both sides by 6.3
h = 38.73
Answer:
14x15-10x10=110
A=110
Step-by-step explanation:
Because it can be written as a fraction 1/3
Answer:
x=-2
Step-by-step explanation:
subtract 8 from both sides you get -4x=-8
divide by -4
you get x=-2
