AC = 9.39 cm

Step-by-step explanation:

sin 80 = m/8

m = 7.88

cos 80 = n/8

n = 1.39

p = 6.5 - 1.39 = 5.11

AC² = 7.88² + 5.11²

AC = 9.39 cm

the correct answer is a.) bc< mn 5 stars if this you : )

step-by-step explanation:

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
