We have some couples of angles that are equal
Answer:
Given : Expression -
To find : How would the sum of cubes formula be used to factor given expression? Explain the process. Do not write the factorization.
Solution :
The formula of sum of cubes is,

First we convert the given expression in 

Apply exponent rule : 

Rewrite 
Therefore,
could be written as 
On comparison with the formula,
a=xy , b=7

When you have a power to a fraction, you simply take it by the top and then by the bottm.
So, split it into two: (2)^4 and (5)^4
Solve: (2)^4=16
(5)^4=625
So the fraction is: 16/625
Check to see if it reduces: It doesn't. (Odd and even numbers that have no common multiples).
Therefore, that's the answer.
<span>Given
∠FHJ = 60°
</span><span>∠FGH = 28°
</span>∠FHG = 180 - ∠FHJ
∠FHG = 180 - 60
∠FHG = 120
∠HFG = 180 - (28 + 120)
∠HFG = 180 - 148
∠HFG = 32
