Answer:
When raising an expression of that format to any power, after grouping like terms, you'll always find that the odd numbered terms are positive, and the even numbered terms are negative.
For example:
(x - y)² = x² − 2xy + y²
(x - y)³ = x³ − 3x²y + 3xy² − y³
(x - y)⁴ =x⁴ − 4x³y + 6x²y² − 4xy³ + y⁴
etc.

Answer:
The measure of the smallest angle of the triangle is 40.
Step-by-step explanation:
A right triangle adds up to 180
x+15+2x+90=180
Combine like terms
3x+105=180
Subtract both sides by 105
3x+105=180
-105=-105
___________
3x=75 Divide by 3
x=25
Plug in 25 for x for equation expression
90=90
25+15=40
2(25)=50
Therefore for the smallest angle is 40
