Answer:
98
Step-by-step explanation:
There are 7 sides to this polygon. Forget all the lettering on the figure. Concentrate on the number of triangles you can count. There are 5 of them. Each one has 180 degrees. So the total number of degrees on the interior of the figure is
5 * 180 = 900
All you have to do is add up all the angles including the x and equate them to 900
x + 146 + 122 +142+ 140 + 110 + 142 = 900 Collect the terms on the left.
x + 802 = 900 Subtract 802 from both sides
x = 900 - 802
x = 98

Step-by-step explanation:
Present dividend, is $2.5
Expected dividends for the next 1, 2, 3 and 4 years denoted by ,
,
,
, respectively will be
=$2.5(1+0.07)=$2.675
=$2.675(1+0.07)=$2.86225
=$2.86225(1+0.07)=$3.0626075
=$3.0626075(1+0.07)=$3.276990025
Present value will be
$2.272727273 + $2.210743802 + $2.150450789 + $2.091802131 + $2.034752982 = $10.76047698
Rounded off to 2 decimal places we get $10.76
