Which relationship is always correct for the angles m, n, and p of triangle abc?
on + p = m
m + p = n
om + p + n = 180 degrees
m + p + n = 90 degrees

m=n+p

Step-by-step explanation:

(180-m)+n+p=180

180+n+p-180=m

m=n+p

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)
