Maurinko [17]

Answer: x³+y³=180

Step-by-step explain: let's remember the formula x³+y³=(x+y)(x²-xy+y²) and also x³+y³=(x+y)³-3xy(x+y) then $\displaystyle\boldsymbol{ x^3+y^3=\underbrace{(x+y)^3}_{6}-3\underbrace{xy}_{2}\underbrace{(x+y)}_6}=\\\\6^3-3\cdot 2\cdot 6=216-36=180$

One fifth of the sum of two angles is 24 and half their difference is 14.Calculate the two angles

Brums [2.3K]

Let, the angles = a, b
It is given that, a+b /5 = 24
a + b = 120 --- equation (1)

a-b/2 = 14
a - b = 28 ---- equation (2)
a = 28 + b

Now, substitute this value of b in equation (1),
28 + b + b = 120
2b = 120 - 28
b = 92/2
b = 46
Now, a = 28 + b = 28 + 46 = 74

In short, Your Angles are 74 and 46

Hope this helps!
