Percent means parts out of 100
74%=74/100=0.74
'of' means multiply
so
128 is 74% of what means
128=0.74 times what
divide both sides by 0.74
172.97297297297297297297297297297=what
the number is about 173
Answer:
0 is the answer
Step-by-step explanation:
You first divide 40 by 19:
19/40=?
Then you convert that to percentage by dropping the decimal point and attaching a %
(hint: you should get 48% about :)
The interior angles of a 9-agon add up to (9 -2)*180° = 1260°. The sum of the given angles is
.. 1139° +x° = 1260°
.. x = 1260 -1139 = 121
The missing angle measure is 121°.
_____
The supplement of each interior angle is its corresponding exterior angle. The sum of exterior angles of any convex polygon is always 360°. Another way to approach this problem is to add the exterior angles.
