The answer of this expression is - 4 1/6
Ok, there are two scenarios here.
1) It's a typo and "<K" should be written as "<J"
if that is the case, we can convert from degrees,minutes,seconds >> degrees like so

once calculated, we get 48.43 degrees.
scenario 2)
<k is the third angle in a right triangle
this would mean that <j + <K + 90 = 180
from the first example, we know that <J = 48.43 degrees
Therefor
48.43 + <k + 90 = 180
48.43 + 90 = 138.43
so
138.43 + <k = 180
Therefor, <K = 41.57 degrees
I really hope this helps!!:)
Answer:
it is 8 thousandths of an inch.
Step-by-step explanation:
3/4 of an inch is .75 of an inch. divide that by 90 an you get 0.008ths of an inch.
Answer:
L=7.94 feet, W=9.88 feet
Step-by-step explanation:
perimeter=78 feet
LxW=78
2L-6=W
substitute
Lx(2L-6)=78
2L^2-6L=78
2L^2-6L-78=0
factor
(2L-15.86)(L+4.95)=0
2L=15.88, L=7.94
L=-7.94 feet
