What is the value of x?

X = 98°

Step-by-step explanation:

53° + 45° + FGH = 180° ( Interior angle property)

FGH = 180° - 98 °

FGH = 82°

Now,

By x would be solved through linear pair.

x° + 82° = 180° ( linear pair)

x° = 180° - 82°

x = 98°

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)
