Find the surface area of the lidless rectangular l=15 cm, b=12 cm, h=14cm​

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.

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°
