Atriangular city lot bounded by three streets has a length of 300 feet on one street, 250 feet on the second, and 420 feet on the third. find the approximate measure of the largest angle formed by these streets.

The approximate measure of the largest angle formed by these streets is

Step-by-step explanation:

we know that

Applying the law of cosines

In this problem we have

----> is the greater side

answer: give more info

step-by-step explanation:

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
