PLEASE HELP ME!! Find the measure of angle A: Find the measure of angle B:

g100num [7]

Answer:

Measure of angle A is 65 degrees and measure of angle B is 37 degrees.

Step-by-step explanation: First add all of the degrees of excluding x (4+(-9)) which is -5. Then subtract that from 180 since that is the sum of all the angles in a triangle which gives you 185. Then divide it by the number of "x's" that there are which is 5 which gives you 37. So angle B is x which is 37 degrees and angle a is 2(37)-9 which is 65 degrees. Hope this helps.

Is 9/16 closest to 0 or 1/2 or 1 is 5/6 closets to 0 or 1/2 or 1

Tema [17]

$\frac{9}{16} > \frac{9}{18}=\frac{1}{2}\\\\\frac{9}{16} < \frac{16}{16}=1\\\\therefore\ \frac{1}{2} < \frac{9}{16} < 1\\\\\frac{9}{16}-\frac{1}{2}=\frac{9}{16}-\frac{8}{16}=\frac{1}{16}\\\\1-\frac{9}{16}=\frac{16}{16}-\frac{9}{16}=\frac{7}{16}\\\\\frac{1}{16} < \frac{7}{16}\\\\Conclusion:\ \frac{9}{16}\ is\ clostes\ to\ \frac{1}{2}$

$other\ 
solution:\\\\\frac{9}{16}=0.5625\\\\\frac{1}{2}=0.5\\\\0.5625-0.5=0.0625\\1-0.5626=0.4375\\\\Conclusion:\frac{9}{16}=0.5625\
 is\ clostes\ to\ \frac{1}{2}=0.5.$

$\frac{5}{6} > 0\\\\\frac{5}{6} > \frac{3}{6}=\frac{1}{2}\\\\\frac{5}{6} < \frac{6}{6}=1\\\\\frac{5}{6}-\frac{1}{2}=\frac{5}{6}-\frac{3}{6}=\frac{2}{6}\\\\1-\frac{5}{6}=\frac{6}{6}-\frac{5}{6}=\frac{1}{6}\\\\\frac{2}{6} > \frac{1}{6}\\\\Conclusion:\frac{5}{6}\ is\ closest\ to\ 1$
