Answer:
Step-by-step explanation:
Use FOIL method
(2 - 7x)(-x + 2) = 2*(-x) + 2*2 + (-7x)*(-x) + (-7x)*2
= -2x + 4 + 7x² - 14x {Combine like terms}
= 7x² - 14x - 2x + 4
= 7x² - 16x + 4
x²(2-7x)(-x + 2)= x² (7x² - 16x + 4)
= x²*7x² - 16x * x² + 4x²
Given:
The ratio of 45-45-90 triangle is .
The hypotenuse of the given isosceles right triangle is .
To find:
The lengths of the other two sides of the given isosceles right triangle.
Solution:
Let be the lengths of the other two sides of the given isosceles right triangle.
From the given information if is clear that he ratio of equal side and hypotenuse is . So,
Therefore, the lengths of the other two sides of the given isosceles right triangle are 7 units.
