Perimeter = 8+8+5+5 = 26 inches.
, which is x<span>≈</span>
Complementary angles: angles whose measures add up to 90 degrees.
x+57=90
x=33 degrees
cosine(33) = 0.83867056794542
0.83867056794542 rounded to the nearest hundredth is 0.84
The correct answer is D) 0.84

Answer:
45 positive numbers have the sum of their digits equal to 8
Step-by-step explanation:
given data
number = 1 to 999
sum n = 8
to find out
positive numbers
solution
we will choose number by this formula
(n+1) (n+2) / 2
here n is 8
so put this value we get number that
positive numbers = (n+1) (n+2) / 2
positive numbers = (8+1) (8+2) / 2
positive numbers = 90 / 2
so 45 positive numbers have the sum of their digits equal to 8
