Answer:
yes you have to use PEMDAS
Step-by-step explanation:
Let x be the measure of both legs since the given is an isosceles right triangle. By the Pythagorean theorem we calculate for the legs,
x² + x² = (5 sqrt 6)²
The value of x from the given equation is approximately 8.66 units.
It will have 2 solutions
2x^2 + 4x + 10= 0
the solutions would have no real roots
