Spanish: Los siguientes ángulos pueden ser las medidas de un triángulo obtusángulo: 36°, 120° y 40°? English: The following angles can be the measurements of an obtuse triangle: 36°, 120° and 40°?

5.5

step-by-step explanation:

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80
