A and b are positive integers and a-b=2 ... Evaluate the following: a) 2^a/2^b
b) 5^a/5^b
c) 4^0.5a/2^b

Step-by-step explanation:

a) 2^{a-b}

b) 5^{a-b}

c) \frac{0.5a}{2^b}

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°
