You would start by subtracting 5-7=2 which would make the equation
3x=x-2 then subtract x from both sides to get 2x=-2 then you would divide both sides by -2 so x=1
Answer:
Step-by-step explanation:
Use the Law of Cosines:
a² = b² + c² - 2ab·cos A
Substituting the given values, we obtain:
a² = (10)² + (7)² - 2(10)(7)·cos 52°
= 100 + 49 - 140·0.6157
= 149 - 86.1926
= 62.81
Taking the square root of both sides yields:
a = 7.925, or (to the nearest degree) 8
Answer:
E
Step-by-step explanation:
Answer:x + y = 54
x - y = 10
Add them to get: 2x = 64
x = 32
and plugging in x = 32 to either equation: y = 22
Ans: the numbers are 22 and 32
