Two angle that form a linear pair are supplementary meaning they add to equal 180° (straight line).
make the bigger angle = x
then smaller angle = x - 30°
x + x - 30 = 180
2x - 30 = 180
2x = 180 + 30
2x = 210
x = 210/2
x = 105
The question is to find the smaller angle which was: x - 30
105 - 30 = 75°

Answer:
<h2>700 (units
)</h2>
Step-by-step explanation:
Surface Area =2 length x width + 2 length x height + 2 height x weight
so we do:
7 x 12 = 84 84 x 2 = 168
7 x 14 = 98 98 x 2 = + 196
14 x 12 = 168 168 x 2= <u> + 336</u>
700
700
The answer would be x=18. First you set it up by setting up an equation;
166=7x+40. Then you subtract 40 from each side. Last, you divide both sides by 7 and you should get x=166 or 166=x.
