A) 5q + 5q + 5
remember to only add like variables
hope this helps
Answer:
It's value is less than 0
Step-by-step explanation:
Answer: 38°
Using cosine rule,
a² = b² + c² -2bc cos(A)
Insert values from diagram
14² = 18² + 22.8² - 2(18)(22.8) cos(A)
196 = 324 + 519.84 - 820.8 cos(A)
-820.8 cos(A) = 196 - 324 - 519.84
-820.8 cos(A) = -647.84
cos(A) = -647.84/-820.8
A = cos^{-1} (-647.84/-820.8)
A = 37.88°
A ≈ 38°
Answer:
0.04
Step-by-step explanation:
Find the number in the hundredth place, in this case its 4
and look one place to the right for the rounding digit, in this case its 3
Round up if this number is greater than or equal to 5
, and round down if it is less than 5.
