After a year of weight training, Harold's weight changed from 172 pounds to 185 pounds. What is his percent increase in weight to the nearest tenth

70.2%

Step-by-step explanation:

Given data

Initial weight =172 pounds

Final weight = 185 pounds

% increase= Final - Initial / final  *100

% increase=185 - 172 / 185 *100

% increase= 13 / 185 *100

% increase=0.0702*100

% increase=70.2%

Hence the increase is 70.2%

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°
