Figure 1. = 1,890 feet squared
figure 2. = 936 feet squared
hello
so to find x, we need to use a rule.
the rule is: the exterior angle of a triangle is equal to the sum of the opposite interior angles.
so our exterior angle is xº, and the opposite interior angles are 53º and 45º.
we could set up a basic equation (although not completely necessary)
xº=53º+45º
xº=98º
hope this helps
have a nice day :)
Answer:
a. x = 14 (see explanation)
b. the arrows along the lines
Step-by-step explanation:
The relationship of these two expressions is Same Side, which means their sum is 180.
<u><em>plugging</em><em> </em><em>in</em></u>
108 + 4x + 16 = 180 | Given
124 + 4x = 180 | Add the numbers
4x = 56 | Subtract 124 from both sides
x = 14 | Divide both sides by 4
I'm not really sure, because 650 marked down by 27% would be 474.5, which is close but not exact.
Hope I helped a little bit, sorry if I'm wrong.
