Answer: total is 200
Step-by-step explanation:
30% = 60
10% = 60/3 = 20
100% = 200
The first integer (x) is equal to the consecutive even integers, x+2, x+4.
x = (x+2) + (x+4)
x = 2x + 6
x - 6 = 2x
x = -6 (First integer)
+2
-4 (Second integer)
+4
-2 (Third integer)
Integers: -6, -4, -2
Equation: x = (x+2) + (x+4)
Answer:
45.2°
Step-by-step explanation:
a = 14
b = 11
c = 10
The Law of Cosines is given as:
arccos (a²+b²﹣c²/2ab)
In this above question, to find m
= arccos(11²+14²﹣10²/2·11·14)
= 45.20717°
Approximately = 45.2°
Option d is the correct answer
