Answer:
Step-by-step explanation:
The most common way to solve for the roots of a polynomial is to use the Quadratic formula, which will return us with two values of x that make the equation equal 0.
...however, this form of the equation is already in root form. If we multiplied these two terms, we'd get , and when we factor that, we'd get -13 and 21.
Roots are usually written in the form , where the zeroes will be the value of x that makes each binomial equal 0 - aka, the opposite of a and b.
The opposite of 13 is -13, and the opposite of -21 is 21.
Therefore, the solutions of this equation are -13 and 21.
Hope this helped!
Answer:
- y = 242.4
- x = 437.3
First find the inner angle:
- 90° - 29°
- 61°
[ given hypotenuse = 500 ft ]
using sine rule:
using pythagoras theorem:
- a² + b² = c²
- y² + (437.3)² = 500²
- y = √58760.1
- y = 242.4
