Given: The shape is a quadrilateral, which means four angles with a sum of 360°. The known measures are 112 and 73, and there are two unknown measures. They are probably identical, considering the fact that they both have the variable x.
Numerically, this would be 
.
Simplify.
= 360
--> 
Isolate the variable by subtracting 185 from both sides.
--> 2x = 175
If 175 is twice as much as x, then 
x = 
Plug in the value of x:
--> 
X has an angle measure of 87.5°
3 1/7 Because there are three multiples of 7 and 1 remainder.
Answer:
Step-by-step explanation:
The answer can be readily calculated using a single variable, x:
Let x = the amount being invested at an annual rate of 10%
Let (8000 - x) = the amount being invested at an annual rate of 12%
The problem is then stated as:
(x * 0.10) + ((8000 - x) * 0.12) = 900
0.10(x) + ((8000 * 0.12) - 0.12(x)) = 900
0.10(x) + 960 - 0.12(x) = 900
0.10(x) - 0.12(x) = 900 - 960
-0.02(x) = -60
-0.02(x) * -100/2 = -60 * -100/2
x = 6000 / 2
x = 3000
Thus, $3,000 is invested at 10% = $300 annually; and $8,000 - $3,000 = $5,000 invested at 12% = $600 annually, which sum to $900 annual investment.
The answer would be (x+1) and (x+10) so E
