x = 8.66 ft
Step-by-step explanation:
cos 30 = adj/hyp = x/10
---> x = (10 ft)cos30
= 8.66 ft
The answer would be (540 - (111 + 103 + 122 + 90[because of the right angle]) and 540 is the total angle measurement of a pentagon (or a 5 sided figure)
ANSWER: n = -16
4n + 13n = 17n
19 + 13 = 32
15 - 17 = -2
n = -16
Answer:
<em>n = 20</em>
Step-by-step explanation:
[ 180° ( n - 2 ) ] / n = 162°
180 ( n - 2 ) = 162 n
180n - 360 = 162n
18n = 360
<em>n = 20</em>
Answer:
I think 478.4 ._.
