Answer: okay so the measure of angle 1 is 72 degrees. Angle 2 is 108 degrees. Angle 3 is 72 degrees. And angle 4 is 108 degrees.
Step-by-step explanation:
I know this because to find angle 1 we are going to subtract 180 degrees from 108 degrees. A straight line like this is 180 degrees. Angle 2 is going to be exactly 108 and angle 3 is also going to be 72 degrees. Angle 4 is 108 degrees because 180-72 is 108
2+2=4
3+2=6
4+6=10
all in total 20
Answer:
100
Step-by-step explanation:
To find the square root of 400 rounded to nearest hundred you have to
1, find the square root of 400 It is √400=√20²=20
2,then round 20 to the nearest hundred which is 100
<u>by</u><u> </u><u>Pythagoras' theorem</u><u> </u>
