Answer:
x = -1.75 , +/- 1.1892i.
Step-by-step explanation:
4x5 + 7x4 + 36x + 63) = (4x + 7)
4x^5 + 7x^4 + 32x + 56 = 0
x^4(4x + 7) + 8(4x + 7) = 0
(x^4 + 8) = 0 or 4x + 7 = 0
4x + 7 = 0
x = -1.75.
4x^4 = -8
x^4 = -2
x = +/- ⁴√-2
x = +/- 1.1892 i.
X would equal 53° since a triangle has to equal 180°, 65 + 62 = 127, 180-127=53°
