What does x equal ???

58

Step-by-step explanation:

since two sides have the same length of 6.2, this is an isosceles triangle, which means that it will also have the same value (61) for two of its angles.

since all 3 angles must add up to 180, you get this equation

A1 + A2 + A3 = 180 where A1 and A2 both equal 61 so

61 + 61 + x = 180

x = 58

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p

⭐⭐

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
